Charlie Munger
Quotes:
"The human mind is a lot like the human egg, in that the human egg has a shut-off device. One sperm gets in, and it shuts down so that the next one can't get in. The human mind has a big tendency of the same sort."- Charlie Munger
Insights:
- Humans face confirmation bias. Once we form negative opinions it is hard to overturn them.
- Rejecters are difficult to convince as they have a pre-existing judgement.
Confirmation Bias
References:
- Albert Hastorf and Hadley Cantril, psychologists - experiment with American football, supporters viewed the game completely differently based on pre-existing loyalties to their own team - students believed that the opposition was twice as likely to commit a foul as their own team.
Examples:
- Government policies are viewed as more favourable by party supporters that by opposition supporters, regardless of the policy.
Insights:
- Confirmation bias occurs when we view the world through the lens of existing feelings or opinion.
- It is difficult to overturn negative opinions.
Principles:
- Do not focus resources on trying to win over rejecters.
Fundamental Attribution Error
Examples:
- When we assume businessmen are selfish and just care about money.
References:
- The Darley & Batson Experiment 1973: Catholic priests stopping to help someone in need was highly influenced by whether they were told they needed to hurry to meet an appointment, not by their character traits.
Insights:
- We consistently underestimate context.
- We may underestimate external factors in our behaviour as we tend to try to rationalise or internalise our decision making.
- Brands should focus on target contexts as much as target audiences since context influences behaviour.
Principles:
- Research little and often.
- Target contexts as well as audiences.
- Don't assume you know the right context.
Injunctive Norms
Definition:
- How we should behave.
Insights:
- Injunctive norms, rather than descriptive ones, can be used to promote behaviour change.
Pratfall Effect
References:
- Elliot Aronson, Harvard University in 1966 - discovered the pratfall effect with Ben Willerman and Joanne Floyd. Experiments with high performing students and likeability. One spills coffee over a new suit, which enhanced their likeability when committing this 'pratfall'.
Insights:
- The admission of weakness can make people or companies more appealing.
- The pratfall effect works well for companies where the competitors like to brag.
- The pratfall effect only works when you are seen to be an expert, or strong brand - it makes strong brands stronger, and weak brands weaker.
Principles:
- Lean into your flaws (when it suits your brand).
Veblen Goods
Definition:
- High price can increase demand.
Examples:
- Perfume.
References:
- Dan Ariely: 2008 experiment with 'painkillers'. Half of the participants were told that the painkillers cost $2.50 a dose, half were told they cost 10 cents. All received placebos. 85% of the participants taking the expensive pill said they experienced less pain, compared to 61% taking the cheaper version.
Insights:
- People tend to have an ingrained belief that expensive products are higher quality.
- Since price signals quality, brands should invest disproportionately towards higher end goods.
- Low prices damage our expectation of product quality. Dropping the price to improve market share might work in the short term, but will likely damage long term demand.
