12 tricks that your mind plays on you

A thread...
Modality effect

You'll tend to remember more when using a mixed-mode (partly visual and partly auditory) of learning compared to a single-mode (either visual or auditory alone)

When information is presented in multiple modalities, total working memory capacity is increased
Next-in-line effect

The tendency to have lower recall for events that happen right before or after a public performance—whether performing on stage or talking to a group of other people

This effect is believed to occur due to both attention distraction and retrograde amnesia
Placement bias

The tendency to be influenced by story placement in the news in a way that downplays information supportive of a minority viewpoint

As a general rule, story placement is a measure of how important the editor considers the story
Picture superiority effect

The tendency for pictures and images to be remembered more easily than words

Occurs because our brains dually encode images, but encode words only once. This means that images are stored as pictures and words, but words are only stored as words
Positivity effect

The tendency for elderly people to perceive and remember positive images and experiences more than negative ones

A form of selective memory that helps compensate for troubles that occur over the lifetime
Processing difficulty effect

We have an easier time remembering information that takes longer to read and understand

This feels counter-intuitive: we want to make our message simple and short, right? In some cases, yes. But, not all. Making the brain work is a powerful tool
Rosy retrospection

Our tendency to recall the past more fondly than the present

An inaccurate view of past events might lead to judging current or future events unfairly. And without storing negative experiences, you may fail to incorporate constructive feedback
Reminiscence bump

The tendency for older adults (over forty) to have increased or enhanced recollection for events that occurred during their adolescence and early adulthood

Occurs because memory storage in autobiographical memory is not consistent through time
Self-relevance effect

A tendency to encode information differently depending on whether we are implicated in the information

When we are asked to remember information when it is related in some way to ourselves, the recall rate can be improved
Source Confusion

A type of memory error where we don't remember where certain memories come from

Dangerous because when we disassociate the content of our knowledge from the source, we become similarly confident in all content despite not being confident in all sources
Suffix effect

The tendency to be unable to recall the final items from a spoken list when the list is followed by an unnecessary or irrelevant speech item or suffix

Occurs because the mind fixates on the very end of the list, even if it's not actually part of the list
Spacing effect

The tendency for learning to be more effective when study sessions are spaced out

Explains why cramming doesn't lead to long-term memory retention, and why repeated exposure over a longer period of time typically does
That's a wrap!

15 concepts I wish I was told when I was younger

A thread...
Trait ascription bias

The tendency for people to view themselves as relatively variable in terms of personality, behavior and mood while viewing others as much more predictable in their personal traits across different situations
Worse-than-average effect

The tendency to underestimate one's achievements and capabilities in relation to others

Related to imposter syndrome and is the opposite of the usually pervasive better-than-average effect (Dunning-Kruger effect)

15 powerful concepts I wish I knew earlier

A thread...
Rhyme as a reason effect

We are more likely to believe statements that contain a rhyme, compared to statements that don't

"Woes unite foes"
"Woes unite enemies"
"Misfortune unites enemies"

Which seems more believable? Be wary of this in advertising or persuasion
Selective perception

The tendency not to notice and more quickly forget stimuli that cause emotional discomfort and contradict our prior beliefs

Can cause issues when you allow small problems to become bigger problems through a lack of appropriate attention

10 concepts to make you a tiny bit smarter than you were yesterday:
Irrational escalation

The phenomenon where people increase their investment in a decision despite new evidence suggesting that the decision was probably wrong

May include money ("throwing good money after bad"), time, or — in the case of military strategy — human lives
Less-is-better effect

People sometimes prefer the worse of two options, but only when the options are presented separately

When people consider both their choices together, their preferences reverse, so that the less-is-better effect disappears

Thread 👇
Decoy Effect

Describes how, when we are choosing between two alternatives, the addition of a third, less attractive option (decoy) can influence our perception of the original two choices Decoy Effect
Distinction Bias

Describes how, in decision-making, we tend to overvalue the differences between two options when we examine them together

Conversely, we consider these differences to be less important when we evaluate the options separately

5 concepts I wish I knew earlier

A thread...
Empathy Gap

Underestimating the way behaviour is largely affected by one’s mental state when you're not currently in that mental state

If you feel calm, you'll find it difficult to predict how you'll act if someone angers you
Meat Paradox

Many of us experience the 'meat paradox', whereby we simultaneously care for animals such as cows, yet also consume them as meat

Applies to many other moral issues where we stay in the 'dark', to protect the illusion that we are morally consistent and sensible
