Appeal to Authority
Tap to reveal the quick meaning.
Remember this
Treating a person’s status or fame as proof instead of checking the actual evidence.
A respected voice can point you toward evidence, but it is not the evidence.
Narrative Fallacy
Preferring a simple, coherent story over the messier and less satisfying reality of how events actually happen.
A satisfying story can still be a weak explanation.
Gambler's Fallacy
Believing a short random streak means the opposite result is now more likely because it feels due.
Random streaks can happen without making the opposite outcome due.
Law of Small Numbers
Assuming a tiny sample will reflect the full pattern even when it is far too small to be reliable.
A few real examples are still just a few examples.
Projection Bias
Assuming other people share your preferences, reactions, motives, or current state more than they actually do.
Your mind is one example, not the default setting for everyone else.
Just-World Hypothesis
Believing the world is fair enough that people usually get the outcomes they deserve, even when luck, injustice, or systems play a major role.
Order is comforting, but the world does not always hand out outcomes fairly.
Ad Hominem
Attacking the person instead of dealing with the claim, evidence, or reasoning.
A flaw in the speaker is not the same thing as a flaw in the argument.
Overconfidence Effect
Feeling more certain than the evidence or skill level actually supports.
Confidence is not the same thing as correctness.
Optimism Bias
Expecting better outcomes and lower risks for yourself or your group than the evidence really supports.
Hope is useful, but it is not the same as a forecast.
Fundamental Attribution Error
Explaining someone else's behavior too much by character and not enough by the situation around them.
Other people's behavior has a situation too.
Moving the Goalposts
Changing the standard of proof or success after someone has already met the earlier standard.
If the finish line keeps moving, the test is not fair.
Whataboutism
Dodging criticism by pointing to another problem somewhere else instead of answering the first one.
Another problem does not erase the problem in front of you.
Keep Going
The goal is not to feel bad. The goal is to notice the bug sooner and choose a better next step.
