Cognitive Biases Flashcards
Placebo effect
If you believe you are taking medicine it can sometimes work even if it’s fake.
The placebo effect can work for stuff that our mind influences (such as pain) but not so much for things like viruses or broken bones. Keep a healthy body and bank balance by using evidence-based medicine from a qualified doctor.
Groupthink
You let the social dynamics of a group situation override (predominar sobre) the best outcome.
Dissent can be uncomfortable and dangerous to one’s social standing, and so often the most confident or first voice will determine group decisions.
Pessimism bias
You overestimate the likelihood of negative outcomes.
Pessimism is often a defense mechanism against disappointment. Perhaps the worst aspect of pessimism is that even if something good happens, you’ll probably feel pessimistic about it anyway.
Sunk cost fallacy
You irrationally cling to things that have already cost you something.
When we’ve invested our time, money, or emotion into something, it hurts to let it go. Ask yourself: had I not already invested something, would I still do so now?
Curse knowledge
Once you understand something you presume it to be obvious.
When teaching someone something new, go slow and explain like they are ten years old (without being patronizing). Repeat key points and facilitate active practice to help embed knowledge.
In-group bias
You unfairly favor those who belong to your group.
We presume that we are fair and impartial, but the truth is that we automatically favor those who are most like us, or belong to our groups. Try to compensate by imagining strangers to be family.
Confirmation bias
You favor things that confirm my existing beliefs.
We are primed to see and agree with ideas that fit our preconceptions, and to ignore and dismiss information that conflicts with them.
“The first principle is that you must not fool yourself-and you are the easiest person to fool” Richard Feynman.
Availability heuristic
Your judgements are influenced by what springs most easily to mind.
How recent, emotionally powerful, or unusual your memories are can make them see more relevant. This, in turn, can cause you to apply them too readily. Try to gain different perspectives and source statistical information.
Self-serving bias
You believe your failures are due to external factors, yet you are personally responsible for your successes.
Many of us enjoy privileges, luck and advantages that others do not. It’s easy to tell ourselves that we deserve things, whilst blaming circumstances when things don’t go our way.
Halo effect
How much you like someone, or how attractive they are, influences your other judgements of them.
If you notice that you are giving consistently high or low marks across the board, it’s worth considering that your judgement may be suffering from the halo effect.
Reactance
You would rather do the opposite of what someone is trying to make you do.
When we feel our liberty is being constrained, our inclination is to resist, however in doing so we can over-compensate. Wisdom springs from reflection, folly from reaction.
Bystander effect
You presume someone else is going to do something in an emergency situation.
When something terrible is happening in a public setting we can experience a kind of shock and mental paralysis. Presume to be the one who will help.
Optimism bias
You overestimate the likelihood of positive outcomes.
There can be benefits to a positive attitude, but it’s unwise to allow this to affect our ability to be realistic. If you make rational judgements you’ll have a lot more to feel positive about.
Negativity bias
You allow negative things to disproportionately influence your thinking.
The pain of loss and hurt are felt more keenly and persistently than the gratification of pleasant things. We are primed for survival, and our aversion to pain can distort our judgement for a modern world.
Prime = preparados
Just world hypothesis
Your preference for a just world makes you presume that it exists.
A world in which people don’t always get what they deserve is an uncomfortable one that threatens our preferred narrative. Try to remember that we are all fallible and bad things happen to good people.
