(Common flaws in our thinking)

The first step in creating change (improvement) is changing the way we think.
Our greatest hurdle:
Our biases, blind spots, cognitive dissonance and natural resistance to changing our deeply ingrained values and beliefs.
One of the most difficult things to see is our presuppositions, our instincts and reflexes, and the contexts within which we operate that create them. What is our current thinking? Where does it come from? How do we tend to act as a result? What are the effects?
Understanding this gives us a point of comparison, a contrast, that puts us in a better position and to be more conscious designers of how we want our organizations to function.
Thinking about our Thinking:
I know you are a rational, logical, tool-making, knowledge-acquiring individual with the proclivity to leverage more than 20% of your assets (human, intellectual, financial, and otherwise), however:
We all have blind spots: There are a number of ways our values and beliefs interfere with our reasoning processes, our perception of reality, how we use information, form beliefs and make decisions.
When you study Deming, brace yourself: Expect mental conflict.
Expect to battle cognitive dissonance: When your world view is confronted with evidence that contradicts it (and it will), you have to do something:
You can either change your entire worldview, which is quite difficult, especially the older you get. Or you dismiss the evidence all together, learning nothing. My advice:
Choose Transformation
Be forewarned: If you are human, your thought process is less than perfect. Quite biased. Hence the statistical reasoning that I implore you to consider. What is a bias?
A bias is favoring or having prejudice against something based on limited information.

The human brain is an incredible processing machine. It can store an amazing amount of information. One way brains are able to store so much information is by creating mental shortcuts based on repeated patterns. These shortcuts allow us to relate and group information together for quicker processing. However,
These repeated patterns of thinking can lead to inaccurate or unreasonable conclusions that are biased — favoring or having prejudice against someone or something. Biases can seriously impact results.
Think of cognitive biases as mental shortcuts that help us make sense of the world. They help us move along without getting bogged down thinking about the meaning of every interaction or event. Just remember:
Unlike random errors, biases lead to systematic patterns of mistakes.
Status quo. Business as usual. Mediocrity.
My personal top of mind biases:
Confirmation Bias: The tendency to favor information that confirms existing beliefs and ignore or downplay contradictory evidence.
Dunning-Kruger effect: On being ignorant of one’s own ignorance. People with low ability, expertise, or experience tend to overestimate their knowledge or competence. Conversely, those with high ability often underestimate their competence. In other words; the less we know, the more confident we may feel – because we do not yet understand what we are missing.
Black and white thinking: Extreme “all or nothing” thinking. Binary, “yes or no.” Nearly opposite of Deming’s statistical probabilistic thinking.
Curse of knowledge: The assumption that other people know as much as we do on a given topic. Meaning; experts are poorer communicators in their own domain than nonexperts.
Here are a few more biases: Apologies for the incomplete and improper format.
- Action bias:
- Describes our tendency to favor action over inaction, often to our benefit. However, sometimes, we feel compelled to act, even if there is not evidence that it will lead to a better outcome than doing nothing would.
- Ex: Inept manager screaming at worker to keep busy even when that busyness is creating waste or non-value add.
- Many organizations value rapid decision-making over slow deliberation. Often this works well to respond to market changes and maintain a competitive edge. However, hasty decision making is at risk of making suboptimal decisions.
- Micromanagement is another consequence of the action bias, when managers are urged to act rather than taking a step back and trusting employees to handle tasks independently.
- Describes our tendency to favor action over inaction, often to our benefit. However, sometimes, we feel compelled to act, even if there is not evidence that it will lead to a better outcome than doing nothing would.
- Actor-observer bias:
- When people attribute their own behaviors to external causes, and the behaviors of others to internal causes.
- Ex: When one person arrives early, and another late. The late person is assumed to have a personality defect…
- Solve the problem instead of figuring who or what to blame
- Be grateful is not any worse
- Stop being so judgmental
- Ex: When one person arrives early, and another late. The late person is assumed to have a personality defect…
- When people attribute their own behaviors to external causes, and the behaviors of others to internal causes.
- Addictive bias:
- Always being right:
- When someone will not admit defeat in the face of compelling evidence against their position. Even the last word may not be enough, only to bring the topic up later.
- Ex: Physicians not acknowledging mistakes (embarrassing and may lead to poor evaluation, censure or even termination.
- Always being right can be wrong, turning people against you, stifling conversations and ideas, and making people want to avoid you.
- Ex: Physicians not acknowledging mistakes (embarrassing and may lead to poor evaluation, censure or even termination.
- When someone will not admit defeat in the face of compelling evidence against their position. Even the last word may not be enough, only to bring the topic up later.
- Ambiguity effect:
- We tend to avoid options that we consider ambiguous or to be missing information. The tendency to avoid options with unknown results, or about which they lack information. Happens when a person given two viable options does not give equal consideration to them both.
- Ex: Considering between three cars and drop the one because warranty information is not on the website.
- Recognize its existence and its influence over our decision making.
- Put in the time and effort to make decisions
- Ex: Considering between three cars and drop the one because warranty information is not on the website.
- We tend to avoid options that we consider ambiguous or to be missing information. The tendency to avoid options with unknown results, or about which they lack information. Happens when a person given two viable options does not give equal consideration to them both.
- Anchoring bias:
- When an individual’s decisions are influenced by a particular reference point or ‘anchor.” The tendency to rely too much on the first piece of information when making decisions.
- Ex: The higher the performance and skill level of the top most employee, the higher the overall level of the other employees.
- Ex: In negotiations: “this is a pretty nice model — they usually go for $20,000 when they’re in such great condition!” ($20k and great condition are the anchors)
- Difficult to mitigate
- When an individual’s decisions are influenced by a particular reference point or ‘anchor.” The tendency to rely too much on the first piece of information when making decisions.
- Anthropocentric thinking:
- The tendency to use human analogies as a basis for reasoning about other, less familiar, biological phenomena.
- Anthropomorphism, aka personification:
- The tendency to characterize animals, objects, and abstract concepts as being possessing human-like traits, emotions and intentions.
- Apophenia:
- The tendency to perceive meaningful connections between unrelated things. (Clustering illusion, illusory correlations, pareidolia.
- Appeal to ignorance:
- Asserts that a proposition is true because it has not yet been proven false. Or, a proposition is false because it has not yet been proven true.
- Ex: Innocent until proven guilty. Aliens are real because no proof says they are not.
- Seek evidence rather than rely on speculation
- Ex: Innocent until proven guilty. Aliens are real because no proof says they are not.
- Asserts that a proposition is true because it has not yet been proven false. Or, a proposition is false because it has not yet been proven true.
- Assumed similarity bias:
- Where an individual assumes that others have more traits in common with them than those others actually do.
- Attribute substitution:
- Attentional bias:
- An error in diagnosis or other form of analysis in which a person is unable to see the truth because he does not perceive a critical piece of data. The tendency to pay attention to some things while simultaneously ignoring others.
- Ex: To pay attention to the positive (liberal) or negative (conservative) words politicians use.
- Practice mindfulness (more aware of self and the present moment)
- Ex: To pay attention to the positive (liberal) or negative (conservative) words politicians use.
- An error in diagnosis or other form of analysis in which a person is unable to see the truth because he does not perceive a critical piece of data. The tendency to pay attention to some things while simultaneously ignoring others.
- Authority bias:
- the tendency to attribute greater accuracy to the opinion of an authority figure (unrelated to its content) and be more influenced by that opinion
- Availability bias:
- When you rush the user recruitment process or skip screener questions to attract a bigger pool of users, even if they do not fit the qualifications or characteristics that you have already determined are present in your ideal user.
- Ex: Marrying the first person you meet after a divorce.
- If you are having trouble recruiting the right users before your deadline, offer a better incentive for participating in your study, adjust your recruitment strategy, or ask your project manager for more time. Do not just take any user who is available.
- Ex: Marrying the first person you meet after a divorce.
- When you rush the user recruitment process or skip screener questions to attract a bigger pool of users, even if they do not fit the qualifications or characteristics that you have already determined are present in your ideal user.
- Availability cascade:
- A self-reinforcing process in which a collective belief gains more and more plausibility through its increasing repetition in public discourse (or “repeat something long enough and it will become true”).
- A self-reinforcing cycle in which information is perceived to be plausible and correct due to its increasing repetition in the public domain. Reaching critical mass…. People are more likely to believe information that is readily available to them.
- Ex: Media covers climate catastrophe, which culminates in a call for legislation.
- Do you own research and come to your own conclusions.
- Ex: Media covers climate catastrophe, which culminates in a call for legislation.
- Availability heuristic:
- We make decisions by relying on information that comes most readily to mind. Mental shortcuts that help us understand the world by using information that is easy to recall. Helps us make fast, but sometimes incorrect assessments.
- Ex: After hearing a news story, you begin to believe that such tragedies are quite common.
- Think before making impulse decisions
- Clear out echo chambers
- Watch overall trends and patterns
- Consider overall statistics
- Ex: After hearing a news story, you begin to believe that such tragedies are quite common.

- Baader-Meinhof phenomenon:
- The illusion where something that has recently come to one’s attention suddenly seems to appear with improbably frequency shortly afterwards.
- Backfire effect:
- The desire to retain their own opinions or false beliefs even when confronted by contradictory evidence. When given evidence is against one’s beliefs, people can reject the evidence and believe it more strongly.
- The tendency to react to disconfirming evidence by strengthening one’s previous beliefs.
- Ex: Conspiracy theorists. Belief that President Obama was not born in U.S.A.
- Recognize where you might suffer from cognitive biases
- Recognize that your beliefs may not be correct
- Be present in the situation and apply different critical thinking skills to assess new information.
- Ex: Conspiracy theorists. Belief that President Obama was not born in U.S.A.
- Bandwagon effect:
- The tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink and herd behavior.
- When we do something primarily because other people are doing it, regardless of our beliefs and knowledge. The tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink and herd behavior.
- Ex: Blindly following your competitors. “If your friends jumped off a bridge…”
- Create distance from the bandwagon cues
- Create optimal conditions for judgement and decision making
- Slow down your reasoning process
- Hold yourself accountable for your decisions
- Examine the bandwagon
- Ex: Blindly following your competitors. “If your friends jumped off a bridge…”
- Barnum effect, or Forer Effect:
- “The fallacy of personal validation.” Refers to the fact that a cleverly worded “personal” description based on general, stereotyped statements will be accepted readily as an accurate self-description by most people. When a person is given a generic personality description that could apply to anyone, but their perception is that it applies uniquely to them. Where individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, yet which are in fact vague and general.
- Ex: Horoscopes
- Be skeptical. Take overly optimistic or generic statements with a pinch of salt. Ask for details.
- Question the sources authority. Trust sources with a good tract record of objectivity and accuracy
- Balance positive and negative
- Ex: Horoscopes
- “The fallacy of personal validation.” Refers to the fact that a cleverly worded “personal” description based on general, stereotyped statements will be accepted readily as an accurate self-description by most people. When a person is given a generic personality description that could apply to anyone, but their perception is that it applies uniquely to them. Where individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, yet which are in fact vague and general.
- Base rate fallacy:
- Occurs when people rely too heavily on prior information (base rates), instead of focusing on the current situation. A decision-making error in which information about the rate of occurrence of some trait in a population (base-rate information) is ignored or not given appropriate weight.
- Ex: Investor presented with to opportunities that vary in terms of the projected risk and return. They may be more likely to choose the riskier option if they are not given sufficient information about its historical performance.
- Pay more attention to base rate information
- Understand that past performance or behavior is not a valid predictor of future performance or behavior
- Consider individual segments of their target audience during product development
- A/B split testing
- Refrain from making statistical inferences in marketing campaigns
- Ex: Investor presented with to opportunities that vary in terms of the projected risk and return. They may be more likely to choose the riskier option if they are not given sufficient information about its historical performance.
- Occurs when people rely too heavily on prior information (base rates), instead of focusing on the current situation. A decision-making error in which information about the rate of occurrence of some trait in a population (base-rate information) is ignored or not given appropriate weight.
- Begging the question, aka circular argument tautology:
- When the premise of an argument presupposes the truth of its conclusion… When the argument takes for granted what it is supposed to prove. Circular reasoning: An argument that requires that the desired conclusion be true.
- Ex: When asked why an exclusive men’s club has such a long waiting line: “the reason there is such a big demand is because everyone wants to get in them.?
- Make sure your conclusion is not a mere rewording of your premises. Do not argue in a circle.
- Ex: When asked why an exclusive men’s club has such a long waiting line: “the reason there is such a big demand is because everyone wants to get in them.?
- When the premise of an argument presupposes the truth of its conclusion… When the argument takes for granted what it is supposed to prove. Circular reasoning: An argument that requires that the desired conclusion be true.
- Belief bias:
- When we decide what is believable based on our knowledge, past experiences, and beliefs, rather than logic. When we accept arguments that align with our preexisting beliefs.
- Ex: In political election, when the loser claims the opponent cheated. When a candidate wins by a slim margin and then proceeds to govern as if they have a mandate befitting of a landslide election.
- Break the argument down into chunks. If A, then B. If B, then C. Therefore, if A, then C. If the premises lead to an accurate conclusion, the argument is valid.
- Distinguish between validity and truth.
- Remain objective
- Ex: In political election, when the loser claims the opponent cheated. When a candidate wins by a slim margin and then proceeds to govern as if they have a mandate befitting of a landslide election.
- When we decide what is believable based on our knowledge, past experiences, and beliefs, rather than logic. When we accept arguments that align with our preexisting beliefs.
- Ben Franklin effect:
- Where a person who has performed a favor for someone is more likely to do another favor for that person than they would be if they had received a favor from that person.
- Berkson’s paradox:
- Black and white thinking:
- All or nothing thinking. Everything is either ALL right or ALL wrong. Absolute
- Ex: Negative thinking. I am the best/worst at…
- Think in terms of probabilities.
- Switch the word Always and Never with Sometimes. All or Nothing becomes Some, Perfect becomes good at some things.
- Ex: Negative thinking. I am the best/worst at…
- All or nothing thinking. Everything is either ALL right or ALL wrong. Absolute
- Bias blind spot:
- When people are unaware of their own biases. Recognizing the impact of biases on the judgment of others, while failing to see the impact of biases on one’s own judgment.
- Ian says he is a better driver than most… right after his third accident this year.
- Increase self-awareness
- Identify who and what makes you uncomfortable
- Educate yourself on the many different cognitive biases
- Ian says he is a better driver than most… right after his third accident this year.
- When people are unaware of their own biases. Recognizing the impact of biases on the judgment of others, while failing to see the impact of biases on one’s own judgment.
- Bizarreness effect:
- Bizarre material is better remembered than common material
- Blaming:
- Where we do not like something and we blame the person, not the environment or circumstances. The practice of strongly and unfairly assigning blame to an individual, group, or organization that is unpopular.
- Ex: A consultant who blames a customer for a product failure in an environment of corporate narcissism where customers are viewed as incompetent and insiders as flawless.
- Own your part
- Set and intention to stop your blaming behavior
- Start paying attention
- Remind others of the 50-50 rule that makes both parties equally accountable
- Ex: A consultant who blames a customer for a product failure in an environment of corporate narcissism where customers are viewed as incompetent and insiders as flawless.
- Where we do not like something and we blame the person, not the environment or circumstances. The practice of strongly and unfairly assigning blame to an individual, group, or organization that is unpopular.
- Boundary extension:
- Remembering the background of an image as being larger or more expensive than the foreground.
- Catastrophizing:
- To imagine the worst possible outcome of an action or event. To view or talk about an event or situation as worse than it actually is.

- Understand thoughts do not define you
- Do not confuse the present with the future
- Get physical
- Ex: If my partner leaves I will never find anyone else and never be happy again.
- To imagine the worst possible outcome of an action or event. To view or talk about an event or situation as worse than it actually is.
- Cheerleader effect: the tendency for people to appear more attractive in a group than in isolation.
- Cherry picking:
- Occurs when someone selects and presents only the evidence that supports their stance while ignoring the evidence that would contradict it.
- Suppressing evidence (or incomplete evidence) by pointing to individual cases or data that seem to confirm a particular position while ignoring a significant portion of related and similar cases or data that may contradict that position.
- Ex: Every advertisement ever written.
- Ex: A news report on gun violence showing footage from shootings, while presenting no statistics about how many people were saved by guns that year.
- Take into account ALL the relevant information available to you, by using various debiasing techniques, such as slowing down your reasoning process and avoiding forming a hypothesis too early
- Childhood amnesia:
- The inability of children and adults to recall events that took place during their infancy and early childhood.
- Ex: What do you remember as a baby?
- Discuss your past encounters and other meaningful incidents
- See childhood photographs
- Visit the places you lived
- Ex: What do you remember as a baby?
- The inability of children and adults to recall events that took place during their infancy and early childhood.
- Choice-supportive bias:
- To retroactively ascribe positive attributes to an option one has selected and/or to demote the forgone options.
- Ex: Buying a share in the stock market because many people believe it will gain value in the future.
- List the pros and cons for each option before making the choice
- Consider the arguments of people who made different choices
- Keep a certain humility and stay flexible in our attitude.
- Ex: Buying a share in the stock market because many people believe it will gain value in the future.
- To retroactively ascribe positive attributes to an option one has selected and/or to demote the forgone options.
- Clustering illusion:
- When people tend see patterns even when there are not any. To expect random events to appear more regular or uniform than they are in reality. The tendency to erroneously consider the inevitable ‘streaks’ or ‘clusters’ arising in small samples from random attributes to be non-random
- In finance, this would be the investor observing patterns in random events.
- To see faces in the clouds or outlines of animals in rocks. The human brain seeks patterns and rules.
- Look for actual trends rather than perceived ones (using statistical analyses such as regression analysis and correlation tests
- Do not jump to conclusions without testing
- Get expert help
- Get larger samples
- When people tend see patterns even when there are not any. To expect random events to appear more regular or uniform than they are in reality. The tendency to erroneously consider the inevitable ‘streaks’ or ‘clusters’ arising in small samples from random attributes to be non-random
- Common source bias:
- The tendency to combine or compare research studies from the same source, or from sources that use the same methodologies or data
- Confirmation bias:
- Occurs when you start looking for evidence to prove a hypothesis you have. When we seek or only listen to information which confirms our preconceptions or, at worst, our misconceptions. To favor information that confirms or strengthens one’s beliefs or values.
- Raymond Nickerson (American psychology professor): “If one were to attempt to identify a single problematic aspect of human reasoning that deserves attention above all others, the confirmation bias would have to be among the candidates for consideration.”
- Pay attention to how you interact with information
- Ask open-ended questions when conducting interviews
- Get into the habit of actively listening without adding your own opinions.
- Include a large sample of users with diverse perspectives.
- Raymond Nickerson (American psychology professor): “If one were to attempt to identify a single problematic aspect of human reasoning that deserves attention above all others, the confirmation bias would have to be among the candidates for consideration.”
- Occurs when you start looking for evidence to prove a hypothesis you have. When we seek or only listen to information which confirms our preconceptions or, at worst, our misconceptions. To favor information that confirms or strengthens one’s beliefs or values.
- Congruence bias:
- To over-rely on testing one’s initial hypothesis (the most congruent one) while neglecting to test alternative hypotheses.
- Ex: Choosing news and media sources that present stories that support your views.
- Ask: How likely is a yes answer, if I assume that my hypothesis is false?
- Think of alternative hypotheses, then choose a test most likely to distinguish them, a test that will probably give different results depending on which is true.
- Ex: Choosing news and media sources that present stories that support your views.
- To over-rely on testing one’s initial hypothesis (the most congruent one) while neglecting to test alternative hypotheses.
- Conjunction fallacy:
- The belief that the conjunction of two events happening is more probable than one happening.
- Ex: If you hear about an earthquake and a tsunami on the same day and think there will be another quake or tsunami soon.
- When hearing a complicated explanation that has too many convenient assumptions or vivid details (a pitch or cause of phenomenon), be aware that each additional assumption lowers the likelihood of it being true.
- When asked to estimate the probability or percentages, think about a finite number, like 100 people.
- Ex: If you hear about an earthquake and a tsunami on the same day and think there will be another quake or tsunami soon.
- The belief that the conjunction of two events happening is more probable than one happening.
- Connotation fallacies (a form of attribution fallacy):
- Occurs when a dysphemistic (derogatory or unpleasant) word is substituted for the speaker’s actual quote and used to discredit the argument.
- Ex: Loony bin versus mental hospital
- Often meant to shock or offend.
- Used to humiliate individuals.
- Ex: Loony bin versus mental hospital
- Occurs when a dysphemistic (derogatory or unpleasant) word is substituted for the speaker’s actual quote and used to discredit the argument.
- Conservatism (or regressive) bias:
- The tendency to favor prior evidence over new evidence and therefore hold onto old opinions even in the face of compelling new insights.
- Ex: In marketing analytics, when new analysis breaks conventional belief, people get defensive and pull up old tests…
- Research every bet you place.
- Allow numbers to make decisions for you
- Remember: without risk there is no reward
- Ex: In marketing analytics, when new analysis breaks conventional belief, people get defensive and pull up old tests…
- The tendency to favor prior evidence over new evidence and therefore hold onto old opinions even in the face of compelling new insights.
- Consistency bias:
- The belief that one’s past actions, thoughts or feelings are the same as they are now. A shortcut; once your brain has committed to something, you no longer have to think about that thing.
- Once we have committed to a course of action or to a belief, we pressure ourselves to conform to that commitment.
- Ex: Habits. And: To gain a sales commitment, the salesperson will have you write down your “commitment.” By getting you to make just a small commitment, a skilled compliance practitioner can get you to make larger and larger ones.
- Listen to your gut (instead of being lured into a compliance trap. Call them out.
- Ask yourself: Knowing what I know now, would I make this decision again?
- Ex: Habits. And: To gain a sales commitment, the salesperson will have you write down your “commitment.” By getting you to make just a small commitment, a skilled compliance practitioner can get you to make larger and larger ones.
- Context effect:
- The context (environmental factors) that surrounds an event effects how an event is perceived and remembered. The influence of environmental factors on one’s perception of a stimulus.
- Ex: Sales strategy of having comfortable flooring – the more comfortable, the more likely you will stick around and shop. Also; the apparent brightness of a stimulus depends not only on its own luminance, but also on that of the surrounding stimulation
- Talk openly about context switching
- Increase the distance between the available options, add more options to the mix,
- Ex: Sales strategy of having comfortable flooring – the more comfortable, the more likely you will stick around and shop. Also; the apparent brightness of a stimulus depends not only on its own luminance, but also on that of the surrounding stimulation
- The context (environmental factors) that surrounds an event effects how an event is perceived and remembered. The influence of environmental factors on one’s perception of a stimulus.
- Continued influence effect:
- Misinformation continues to influence memory and reasoning about an event, despite the misinformation having been corrected. Where the original memory is affected by incorrect information received later.
- Contrast effect:
- The bias that distorts our perception of something when we compare it to something else, by enhancing the differences between them.
- Ex: Enhance your beauty by hanging with ugly people. Some optical illusions.
- In HR, use a structured interview process
- Ex: Enhance your beauty by hanging with ugly people. Some optical illusions.
- The bias that distorts our perception of something when we compare it to something else, by enhancing the differences between them.
- Courtesy bias:
- The tendency to give an opinion that is more socially correct than one’s true opinion, so as to avoid offending anyone.
- Cross-race effect:
- The tendency for people of one race to have difficulty identifying members or a race other than their own.
- Converse accident fallacy:
- Occurs when a rule that applies only to an exceptional case is wrongly applied to all cases in general. Arguing from a qualified position or particular case to an unqualified and general rule. Known as fallacies of presumption.
- Ex: Because patients with certain illnesses are permitted to use marijuana, marijuana should be legal for everyone.
- Avoid hasty generalizations
- Ex: Because patients with certain illnesses are permitted to use marijuana, marijuana should be legal for everyone.
- Occurs when a rule that applies only to an exceptional case is wrongly applied to all cases in general. Arguing from a qualified position or particular case to an unqualified and general rule. Known as fallacies of presumption.
- Cross-race effect:
- The tendency to more easily recognize and remember faces that belong to one’s own racial group.
- Ex: All Asians looking people are Chinese
- Seek continual exposure to ethnic groups that differ from your own
- Ex: All Asians looking people are Chinese
- The tendency to more easily recognize and remember faces that belong to one’s own racial group.
- Cryptomnesia:
- An implicit memory phenomenon in which people mistakenly believe that a current thought or idea is a product of their own creation when in fact they have encountered it previously and forgotten about it.
- The reappearance of a suppressed or forgotten memory that is mistaken for a new experience.
- Accidental joke stealing and plagiarism
- Know it is possible
- Know the form it is likely to take
- Seek outside opinions
- Accept that minor cryptomnesia will happen
- Accidental joke stealing and plagiarism
- Curse of knowledge:
- Occurs when an individual, who is communicating with other individuals, assumes that the other individuals have the background knowledge to understand. When we incorrectly assume that everyone knows as much as we do on a given topic.
- Ex: Experts are poorer communicators in their own domain than nonexperts.
- Know your audience’s base subject knowledge
- Tone down your vocabulary
- Tell a story
- Ditch abstractions
- Provide examples
- Use visuals.
- Ex: Experts are poorer communicators in their own domain than nonexperts.
- Occurs when an individual, who is communicating with other individuals, assumes that the other individuals have the background knowledge to understand. When we incorrectly assume that everyone knows as much as we do on a given topic.
- Declinism:
- Decoy effect, attraction effect, asymmetric dominance effect:
- When consumers change their preference between two options when presented with a third option.
- Ex: Slight upsell. The decoy is priced to make on the other options much more attractive.
- Focus on only buying as much as you really need, and clarify ahead of time what characteristics are most important to you.
- Ex: Slight upsell. The decoy is priced to make on the other options much more attractive.
- When consumers change their preference between two options when presented with a third option.
- Defensive attribution hypothesis:
- A term where an observer attributes the causes for a mishap to minimize their fear of being a victim or cause in a similar situation.
- We have a tendency to attribute a cause to events. We find it uncomfortable to think that events happen by chance or by accident. If things happen by chance, then bad things could happen to us at any time. Therefore, we make an attribution error. This is a nifty trick to defend us from discomfort.
- Ex: Played out in auto accidents, natural disasters, muggings, rapes and robberies, etc.
- Get comfortable with discomfort
- Consider chaos
- Think about external factors
- Ex: Played out in auto accidents, natural disasters, muggings, rapes and robberies, etc.
- Denomination effect:
- People may be less likely to spend larger denominations than their equivalent in smaller denominations.
- Ex: May spend twenty $1 bills rather than a $20 bill.
- When investing, think of a company holistically rather than just focusing on the price at which it is trading.
- Carry larger, prettier bills
- Carefully evaluate the value of money that is being spent, regardless of the denomination of the currency, and to make decisions that are based on the overall value of money rather than the denomination of the bills.
- Ex: May spend twenty $1 bills rather than a $20 bill.
- People may be less likely to spend larger denominations than their equivalent in smaller denominations.
- Denying the antecedent:
- When it is assumed in an “If/ then” statement, that if the first part of the statement (if) is false, then the second part (then) must also be false.
- Ex: If Jane works harder than John, then she will get a job. John does not work harder than Jane. Therefore, John will not get a job.
- Approach arguments critically. Back up ideas with evidence and consider other possible explanations.
- Ex: If Jane works harder than John, then she will get a job. John does not work harder than Jane. Therefore, John will not get a job.
- When it is assumed in an “If/ then” statement, that if the first part of the statement (if) is false, then the second part (then) must also be false.
- Disposition effect:
- Disqualifying the positive:
- Treating positive events like flukes, thereby clinging to a more negative worldview and set of low expectations for the future.
- Ex: Jane delivers a great musical performance. Everyone congratulates her. She responds by saying “Thanks, but I hit a wrong note. Didn’t you notice?”
- Ex: When all you focus on throughout the day is getting stuck in traffic, when many other positive things happened.
- Recognize when it is happening
- Look at the facts
- Do a cost-benefit analysis
- Find things you are grateful for
- Practice receiving positive feedback
- Treating positive events like flukes, thereby clinging to a more negative worldview and set of low expectations for the future.
- Distinction bias:
- The tendency to overvalue the differences between two options when they are compared side by side, rather than when they are evaluated separately.
- The tendency to view two options as more distinctive when evaluating them simultaneously than when evaluating them separately.

- Dunning-Kruger effect:
- The Dunning-Kruger effect reveals how individuals with limited experience tend to overestimate their skills and knowledge due to the unawareness of what they don’t know.
- Ignorant of your own ignorance
- Occurs when a person’s lack of knowledge and skills in a certain area causes them to overestimate their own competence. By contrast, this effect also causes those who excel in a given area to think the task is simple for everyone, and underestimate their relative abilities as well.
- Ex: When underperformers grossly overestimate their ability to do something
- When someone is not only really bad at an activity, but is also unable to realize that they are bad because of how bad they are at that activity.
- The irony of the Dunning-Kruger Effect is that, Professor Dunning notes, “the knowledge and intelligence that are required to be good at a task are often the same qualities needed to recognize that one is not good at that task—and if one lacks such knowledge and intelligence, one remains ignorant that one is not good at that task.”
