An imperfect mind: Irrationality & Hypnosis Flashcards
Humans are not constructed with a perfect mind
We are vulnerable.
& don’t control most of our choices.
Two minds? System 1 & 2
System 1: automatic, autonomous, bottom-up (processing as it comes in via senses), heuristic, little effort.
- eg. face and word recognition, implicit learning.
System 2: controlled, effortful, rule based, top-down (perception driven by cognition), slow.
- supposedly oversees processing in system 1.
- eg. conscious problem solving, explicit recall, financial decisions, fairness judgements.
All processes have an automatic and a thought component.
System 1: Who is in control?: priming guilt
W _ _ H & S _ _ P ?
- said WASH and SOAP if primed guilt before hand; otherwise WISH and SOUP (Kahneman, 2011).
Those induced into washing hands with soap after admitting a past wrong, exhibited less helpful behaviour in a subsequent task (Xu et al, 2014) = The Lady Macbeth effect.
System 1: Who is in control?: priming self-centeredness
Put money in the background and not draw attention to it (Wohs et al, 2006).:
- money primed ppts persevered twice as long solving difficult problem - better self reliance.
- less willing to help other students - more self centred.
- preferred to play/work alone and put more physical distance between themselves and new acquaintance - less sociable.
System 1: Who is in control?: priming slow action
Asked to make sentence out of 5 words (Bargh et al, 1996):
- those exposed to words related to the elderly walked slower when leaving - subconsciously inhabited.
- ppts had no idea.
System 1: Who is in control?: we live much by system 1 - choice blindness
Think you have made a reasoned decision?
- asked which of 2 face is more attractive and explain why; choice was swapped.
- people justified decisions they didn’t make due to system 1 processing.
System 2 to override 1?: decision fatigue
Researchers analysed 1100+ judges parole decisions:
- parole more likely in the morning.
- decisions not solely based on laws and facts (Danziger et al, 2011).
Also more likely to get parole just after lunch (Baumeister & Tierney, 2011).
System 2 to override 1?: ego depletion
Willpower is a resource that can be depleted.
- after participants resisted baked cookies, less likely to resist temptations later (Baumeister & Tierney, 2011).
But if you eat more glucose you get more willpower - catch 22.
Effort rationality: the need for more effortful thinking - bat & ball Q
Brain does not wilfully engage in effortful thinking (would automatically say 10p).
- driven by need to balance resources, drives human behaviour.
- vulnerable to certain types of errors.
High IQ is not guarantee against this type of error.
- MIT and Harvard students = cognitive misers (Stanovich, 2009).
Effort rationality: more miserliness - Levesque’s Anne problem
Is a married person looking at an unmarried person?
- brain is fallible and not willing to expend effort and resources for rational thinking.
- saving for other situations?
High IQ people only slightly more likely to spontaneously adopt fully disjunctive reasoning.
- if asked to reason through the problem, high IQ people would be more efficient.
Effort rationality: why are we cognitive misers?
Despite changes in the brain we have more generally evolved to increase reproductive fitness of genes not to increase rationality.
Evolution does not guarantee perfect epistemic rationality.
- accuracy requires energy, memory and attention.
- often lack these requirements for rational cognition to establish the truth.
Effort rationality: model of the mind based on the dual-process theory
System 1: in control - do a lot of things based on outputs of 1.
- seems to do most of the work.
2: not infallible/perfect - don’t even use them.
- brain will turn off this system.
- doesn’t get involved too often.
Effort rationality: Stanovich, 2009
Autonomous mind (1): priming, word reading/interference in stroop task -> response.
(pre-attentive process) -> algorithmic mind (2): supervisory processes, lateral & polar PFC -> (override) autonomous mind (1).
algorithmic mind (2) -> top end = high IQ/abstract problem solving ability, Flynn effect and violence reduction.
Why override if there isn’t a better response?
- to determine this, need to stimulate its effect?
Requires hypothetical reasoning.
- must represent current goal state and an alternative.
Representational abuse = confusion of representation states.
Need to be able to become unhooked from the real world.
- primary vs. decouples/unhooked secondary representations of the world.
Stereotypes: reflective mind initiates their override.
Reason & rationality: Stanovich (2009) - a third type of mind
Type 3 questions goals of system computation (mind 2) processes/beliefs/cognitive styles etc.
Reflective mind: eg. thinking dispositions, superstitious thinking, dogmatism (principles without consideration of evidence and other opinions), stereotypes.
- could still have high IQ but poor reflective mind.
- smart people support stupid things.
Aim to get reflective mind as efficient as possible - most important.
- assessed at uni.
- teaches us to use it - take away evidence based learning.
Reflective mind = important way of thinking about the mind and abilities we want humans to use and to be better.
Reason & rationality: Stanovich (2009)
Stimulation from algorithmic mind (2) deriving alternative response leads to reflective mind (3).
= individual differences in rational thinking dispositions; memes.
-> response //
-> top end = well-calibrated beliefs; acting appropriately in line with those beliefs.
Reason & rationality: mindware & memes
Accumulate mindware or memes.
Learned thinking dispositions/beliefs are not always positive as in the case of reduced violence.
- superstitious thinking, dogmatism, stereotypes = memes.
We should use evidence based reasoning (rational) and dispense with beliefs/thinking dispositions that do not match evidence.
- don’t always - sometimes we’re irrational.
Reason & rationality: an evolved mind?
Rationality (reason) is the cultural invention (meme) that truly trumps genetic interests (Stanovich & West, 2003).
- sometimes we are too lazy to employ it.
- memes (mindware) can be acquired reflectively or non-reflectively (Stanovich & West, 2003).
