Study Notes

Reasoning Errors

We are more likely to detect reasoning errors in others than in ourselves (bias blind spot).
We overestimate our own abilities and prospects (self-overestimation).
We accept arguments based on how plausible the conclusion sounds, rather than its logic (belief bias).
We overestimate the likelihood of an event happening after it has occurred (hindsight bias).
We assume individuals from a specific group share certain traits without knowing them personally (stereotyping).

Investor/Consumer Reasoning Errors

We remember our past choices as better than they actually were (choice supportive bias).
We value something more simply because we own it (endowment effect).
We blindly follow the behavior of our group (bandwagon effect).
A piece of information can heavily sway our estimations (anchoring).
We draw different conclusions from the same information based on how it's presented (framing effect).
We feel the negative impact of loss more strongly than the positive impact of gain (loss aversion).
We consider sunk costs when deciding if to continue a project, even if those costs are irrecoverable (sunk cost fallacy).

Statistical/Mathematical Reasoning Errors

We struggle to accurately estimate probabilities (statistical reasoning errors).
We ignore base rates when estimating the probability of an event (base rate fallacy).
We overestimate the likelihood of an event occurring if it's easy to recall or imagine (availability bias).
We expect statistically improbable events to occur (gambler's fallacy).
We perceive patterns in randomness (hyperactive pattern detection).
We underestimate exponential growth (exponential reasoning errors).

The Peculiar Architect of Our Thinking

Our thinking apparatus evolved through natural selection.
Evolution favors traits that increase reproduction, even if they are not entirely accurate.
System 1 thinking is fast, intuitive, and automatic. It's usually in control.
System 2 thinking is slow, conscious, and requires effort. It checks the output of System 1.

The Fallibility of System 1

It uses heuristics as a shortcut, leading to approximations.
It prioritizes avoiding costly mistakes over accuracy.
It's designed for our evolutionary past, not necessarily our current environment.

Heuristics: Simplicity Trumps Complexity

System 1 relies on simple rules of thumb to make quick decisions.
This can lead to errors, especially when the context changes.

Error Management

Avoiding costly mistakes is more important to System 1 than accuracy.
This can lead to biased decisions, especially when under pressure.

Evolutionary Mismatch

Our heuristics are designed to help us navigate our historical environment, not our current one.
This can lead to us applying outdated strategies in current scenarios.

Other Sources of Irrationality

Our social environment influences how we think and behave.
We can benefit from deceiving others, which can lead to self-delusions.
System 2 also suffers from biases, particularly from its role in the social environment.

The Irrationality of System 2

We can be swayed by tradition or authority even if it isn't logical or beneficial.
Religion can exploit our cognitive biases and lead to widespread irrationality.
Our tendency to find patterns, see minds in inanimate objects, and rely on teleological explanations contribute to supernatural beliefs.

The Myth of Homo Economicus

Traditional economics assumes humans are rational, but reality is different.
We are prone to anchoring, framing, and other biases that affect our economic choices.

Mastering Critical Thinking

Our reasoning errors stem from:
- Intuitive thinking (System 1)
- Interference with emotions
- Confirmation bias and overconfidence bias

There is No Off Switch for System 1

System 1 operates constantly, even when we are trying to be rational.
We may not always be aware of its influence on our thinking.

Can We Ever Trust Our Intuition?

It depends on the source:
- Innate intuitions are powerful, but shaped by evolution.
- Acquired intuitions are based on experience and can be more reliable.

Ecological Rationality

Heuristics are not inherently misleading, but tools adapted to specific situations.
They can be effective when applied correctly, but can lead to errors if misused.

Science and the Self-Correcting Process

Scientific methodology and framework protect scientists from cognitive biases.
Peer review and replication ensure accuracy.
Meta-analysis helps to combine research and avoid distorted results.
Research transparency (methods and results) fosters integrity and scrutiny.

The Power of the Community

Scientific progress relies on collaboration and open criticism.
Scientists work together to identify and correct errors.

Importance of Scientific Progress

Advancement in science improves living standards and societal well-being.
Human sciences are crucial for understanding ourselves and creating a better society.

Self-Censorship in the Human Sciences

Scientists may avoid controversial topics due to fear of social consequences.
This hinders progress in understanding complex human issues.

The Demarcation Criterion

Science should not be self-censored but seek truth inclusively.
This includes examining even uncomfortable or controversial topics.
