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)
Ultimate Attribution error

We tend to attribute good acts by friends to their character, and bad acts by friends to situational factors

For enemies (or people we dislike), it’s reversed: good acts are attributed to situational factors and bad acts to character
Change bias

Remembering the past as more difficult than it actually was

After exerting effort and causing a change in some area, this bias makes you believe your journey and work were more difficult than they actually were

"When I was a boy... things weren't so easy"
Childhood amnesia

The inability of adults to retrieve memories before the age of two to four years, as well as the period before the age of ten, of which some older adults retain fewer memories than might otherwise be expected given the passage of time
Context effect

An event is more favourably perceived and remembered when the surrounding environment is comfortable and appealing
Cross-race effect

A facial recognition phenomenon in which individuals show superior performance in identifying faces of their own race when compared with memory for faces of another, less familiar race
Fading affect bias

The tendency for memories associated with negative emotions to be forgotten more quickly than those associated with positive emotions

This helps us forget bad experiences more readily
Generation effect (Self-generation effect)

The tendency for information to be better remembered when it is self-generated as opposed to passively consumed

Explains why active recall is one of the most effective learning and retention techniques
Humor effect

The tendency for humorous items to be remembered more easily than non-humorous ones

Potentially explained by the increased cognitive processing time to understand the humor, or the emotional arousal caused by the humor
Lag effect

We retain information better when there are longer breaks between repeated presentations of that information

The lag effect suggests that the longer the time between repetitions of information, the more likely we are to commit that information to memory
Levelling and sharpening

Levelling and sharpening are processes we use during memory recollection

Levelling refers to the tendency to omit minor details and distinctions, whereas sharpening occurs when certain aspects of a memory are exaggerated or made more profound
List-length effect

As the length of a list gets longer, a greater number of items are actually remembered

When you go shopping and forget your list, you remember only a few items—this happens whether it's a short or a long list. If it's long, you'll tend to remember more
Misinformation effect

The tendency for post-event information to interfere with the memory of the original event

For example, if a question contains misleading information, it can distort the memory of an event. This can lead to inaccurate or false memories
Misattribution of memory effect

The tendency to remember what took place and the specific piece of information, but not where it came from

"I've heard about this, but I can't remember where from, so it's hard to justify it"
That's a wrap!

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

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

10 concepts for better thinking:

Thread 👇

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
