2.1 Malcolm Gladwell
📖 Our decisions are often influenced by unconscious biases and assumptions.
“Beware of the seductive appeal of the familiar.”
— Malcolm Gladwell, Blink: The Power of Thinking Without Thinking
We tend to favor information and people that confirm our existing beliefs, which can lead us to make poor decisions.
“Be aware of your unconscious biases.”
— Malcolm Gladwell, Talking to Strangers
We are all susceptible to unconscious biases that can influence our decisions and interactions with others. It is important to be aware of these biases and to try to mitigate their impact.
“Trust your gut, but also be willing to challenge it.”
— Malcolm Gladwell, Outliers
Our instincts can be valuable, but they can also be misleading. It is important to be able to trust your gut, but you should also be willing to question it and to seek out additional information before making a decision.
2.2 Daniel Kahneman
📖 We tend to be overconfident in our beliefs and decisions.
“We are overconfident in our beliefs and decisions.”
— Daniel Kahneman, Thinking, Fast and Slow
Kahneman’s research has shown that people are often overconfident in their beliefs and decisions. This overconfidence can lead to a number of problems, including: making poor decisions, failing to take into account important information, and being unwilling to change our minds when presented with new evidence.
“We are more likely to believe information that confirms our existing beliefs.”
— Daniel Kahneman, Thinking, Fast and Slow
Kahneman’s research has also shown that people are more likely to believe information that confirms their existing beliefs. This is because our brains are wired to seek out information that confirms our beliefs and to ignore information that contradicts them. This can lead to a number of problems, including: becoming more entrenched in our beliefs, even when they are wrong, and being less open to new ideas.
“We are more likely to make decisions when we feel positive.”
— Daniel Kahneman, Thinking, Fast and Slow
Kahneman’s research has shown that people are more likely to make decisions when they feel positive. This is because positive emotions make us more optimistic and more willing to take risks. This can lead to a number of problems, including: making poor decisions when we are feeling good, and failing to take into account important information when we are feeling bad.
2.3 Chip Heath and Dan Heath
📖 The most effective decisions are made when we consider both the emotional and logical aspects of the situation.
“To make the most effective decisions, we need to integrate both logical and emotional thinking.”
— Chip Heath and Dan Heath, Decisive: How to Make Better Choices in Life and Work
Our emotions provide us with valuable information about our needs and values. By ignoring our emotions, we are more likely to make decisions that we will later regret.
“We should not rely on our intuition alone when making decisions.”
— Chip Heath and Dan Heath, Decisive: How to Make Better Choices in Life and Work
Our intuition is often biased by our past experiences and our current emotions. By taking the time to consider all of the available information, we can make more informed decisions.
“We should not be afraid to ask for help when making decisions.”
— Chip Heath and Dan Heath, Decisive: How to Make Better Choices in Life and Work
Other people can provide us with valuable perspectives and insights that we may not have considered on our own.
2.4 Barry Schwartz
📖 Having too many choices can actually make it harder to make a decision.
“The paradox of choice claims that having too many choices can make it harder to make a decision.”
— Barry Schwartz, The Paradox of Choice: Why More Is Less
When people have too many choices, they can become overwhelmed and paralyzed by indecision. This is because they have to spend more time and effort evaluating each option, which can lead to decision fatigue.
“The optimal number of choices is limited.”
— Barry Schwartz, The Paradox of Choice: Why More Is Less
Schwartz found that people are most satisfied with their choices when they have a limited number of options to choose from. This is because they are able to evaluate each option more carefully and make a more informed decision.
“Having too many choices can lead to regret.”
— Barry Schwartz, The Paradox of Choice: Why More Is Less
When people have too many choices, they are more likely to second-guess their decision and experience regret. This is because they are more likely to compare their choice to other options that they did not choose.
2.5 Gerd Gigerenzer
📖 In many cases, simple decision-making rules can be just as effective as complex ones.
“Use simple rules for tough decisions.”
— Gerd Gigerenzer, https://www.edge.org/response-detail/26815
Complex decisions can often be made just as effectively using simple rules. This is because simple rules are easier to apply and understand, and they can often lead to better outcomes than complex rules.
“Don’t try to be perfect.”
— Gerd Gigerenzer, https://www.psychologytoday.com/us/blog/the-decision-maker/201404/the-paradox-of-choice-why-less-more
When making decisions, it is important to remember that there is no such thing as a perfect decision. Trying to be perfect can lead to overthinking and indecision. It is better to make a good decision that is good enough, rather than trying to make the perfect decision that never comes.
“Trust your gut.”
— Gerd Gigerenzer, https://www.scientificamerican.com/article/the-power-of-intuition/
Our intuition is often a valuable tool for making decisions. It can help us to quickly and efficiently assess a situation and make a decision that is right for us. While it is important to use our rational mind to make decisions, we should not ignore our intuition.
2.6 Cass Sunstein
📖 Nudging people in the right direction can help them make better decisions.
“Changing the default options can lead to significant changes in people’s behavior.”
— Cass Sunstein, Nudge: Improving Decisions About Health, Wealth, and Happiness
For example, if you make it the default option for people to donate their organs, more people will donate their organs. This is because people are more likely to stick with the default option than to change it.
“People are more likely to do something if they are told that others are doing it.”
— Cass Sunstein, Nudge: Improving Decisions About Health, Wealth, and Happiness
This is known as social proof. For example, if you see a lot of people wearing a certain type of clothing, you are more likely to wear that type of clothing yourself.
“People are more likely to make a decision if they are given a clear and simple choice.”
— Cass Sunstein, Nudge: Improving Decisions About Health, Wealth, and Happiness
For example, if you want people to save more money, you should make it easy for them to do so. You could do this by setting up a automatic savings plan.
2.7 David Dunning
📖 People who are incompetent at a task are often unaware of their own incompetence.
“People who are incompetent at a task are often unaware of their own incompetence.”
— David Dunning, Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments
This finding is known as the Dunning-Kruger effect, and it has been replicated in many different studies. It suggests that people who are bad at something are often not aware of their own incompetence.
“The Dunning-Kruger effect can be explained by a number of factors, including:”
— David Dunning, Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments
- Self-serving bias: People tend to attribute their successes to their own abilities and their failures to external factors.
- Illusion of transparency: People believe that their own thoughts and feelings are obvious to others, even when they are not.
- Egocentric bias: People tend to overestimate their own abilities and importance.
“The Dunning-Kruger effect can have a number of negative consequences, including:”
— David Dunning, Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments
- Poor decision-making: People who are unaware of their own incompetence are more likely to make bad decisions.
- Lack of motivation: People who believe that they are good at something are less likely to put in the effort to improve their skills.
- Conflict and misunderstandings: People who are unaware of their own incompetence are more likely to get into conflict with others.
2.8 Daniel Gilbert
📖 We are often bad at predicting what will make us happy.
“Our predictions of future happiness are often inaccurate because we fail to take into account how our preferences will change over time.”
— Daniel Gilbert, Stumbling on Happiness
We tend to think that we will always want the same things, but our desires and priorities often change as we experience new things and learn more about ourselves. This can lead us to make decisions that we later regret.
“We are more likely to be happy when we focus on experiences rather than material possessions.”
— Daniel Gilbert, Stumbling on Happiness
Experiences create memories that we can cherish for a lifetime, while material possessions often lose their luster over time. This is because experiences provide us with opportunities for growth and connection, while material possessions do not.
“We should not be afraid to change our minds.”
— Daniel Gilbert, TED Talk: The Science of Happiness
It is perfectly normal to change our minds as we learn new information and gain new experiences. In fact, it is a sign of intelligence and growth. We should not be afraid to admit when we were wrong and to make changes accordingly.
2.9 Sendhil Mullainathan and Eldar Shafir
📖 Poverty can lead to cognitive impairments that make it difficult to make good decisions.
“Poverty is not a lack of character but a lack of resources.”
— Sendhil Mullainathan and Eldar Shafir, Scarcity: Why Having Too Little Means So Much
People in poverty often make decisions that seem irrational to those who are not in poverty. This is because poverty creates a scarcity mindset, which leads people to focus on short-term needs and to make decisions that are not in their long-term best interests. For example, people in poverty may be more likely to take out high-interest loans or to buy unhealthy food because they are focused on getting their immediate needs met.
“The cognitive impairments caused by poverty can be reduced by providing people with resources.”
— Sendhil Mullainathan and Eldar Shafir, Scarcity: Why Having Too Little Means So Much
Studies have shown that providing people in poverty with resources, such as money or food, can help to reduce the cognitive impairments caused by poverty. For example, one study found that giving people in poverty a small amount of money each month led to improvements in their cognitive function and decision-making. Another study found that providing people in poverty with food assistance led to improvements in their children’s cognitive development.
“It is important to be aware of the cognitive impairments caused by poverty so that we can make better decisions about how to help people in need.”
— Sendhil Mullainathan and Eldar Shafir, Scarcity: Why Having Too Little Means So Much
When we understand the cognitive impairments caused by poverty, we can make better decisions about how to help people in need. For example, we can design programs that are tailored to the needs of people in poverty and that help to reduce the cognitive impairments caused by poverty. We can also make changes to our policies and practices that make it easier for people in poverty to access resources and to make good decisions.
2.10 Lee Ross
📖 We tend to see what we want to see, and ignore evidence that contradicts our beliefs.
“Confirmation bias leads us to evaluate new evidence in a one-sided way, seeking out information that confirms our existing beliefs while ignoring or discounting anything that contradicts them.”
— Lee Ross, The Psychology of Confirmation Bias
Confirmation bias is a cognitive bias that causes us to seek out and interpret information in a way that confirms our existing beliefs, while ignoring or discounting anything that contradicts them. This can lead us to make poor decisions and to be less open to new ideas.
“Confirmation bias can be reduced by actively seeking out information that contradicts our existing beliefs.”
— Lee Ross, Reducing Confirmation Bias: The Importance of Considering Alternative Viewpoints
One way to reduce confirmation bias is to actively seek out information that contradicts our existing beliefs. This can be difficult, but it is important to do if we want to make more informed decisions and be more open to new ideas.
“Confirmation bias is a powerful force, but it can be overcome with effort and mindfulness.”
— Lee Ross, The Power of Confirmation Bias: How to Overcome It
Confirmation bias is a powerful force, but it can be overcome with effort and mindfulness. By being aware of our own biases and actively seeking out information that contradicts our beliefs, we can make more informed decisions and be more open to new ideas.
