Kahneman tells a short story about a visit he and his wife made years ago to Vancouver Island. Fully 81% of the entrepreneurs put their personal odds at 7 out 10 higher, and 33% said their chance of failing was zero. The bias was more glaring when people assessed the odds of their own venture. A survey found that American entrepreneurs tend to believe they are in a promising line of business: their average estimate of the chances of success for ‘any business like yours’ was 60% – almost double the true value. But the individuals who open such businesses do not believe that the statistics apply to them. The chances that a small business will survive for five years in the United States are about 35%. However, optimism can lead to delusional tendencies, particularly for entrepreneurs. They are talented and they have been lucky, almost certainly luckier than they acknowledge… the people who have the greatest influence on the lives of others are likely to be optimistic and overconfident, and to take more risks than they realise. They got to where they are by seeking challenges and taking risks. Their decisions make a difference they are the inventors, the entrepreneurs, the political and military leaders – not average people. Optimistic individuals play a disproportionate role in shaping our lives. Optimists are normally cheerful and happy, and therefore popular they are resilient in adapting to failures and hardships, their chances of clinical depression are reduced, their immune system is stronger, they take better care of their health, they feel healthier than others and are in fact likely to live longer. If you are allowed one wish for your child, seriously consider wishing him or her optimism. He advises that you be both happy and wary if you are temperamentally Significant of the cognitive biases” because it can be both a blessing andĪ risk. The Optimistic Bias (and its benefits)įor Kahneman, the optimistic bias “may well be the most When it comes to entrepreneurship, we have some very obvious cognitive biases, as Kahneman explains in Chapter 24: The Engine of Capitalism. your political preference determines the arguments that you find compelling) and confirmation bias (the tendency to only seek out information that supports your existing viewpoint) and you start to realise why we’re facing such challenging political times. Throw in the affect heuristic (in which people let their likes and dislikes determine their beliefs about the world i.e. Stories are easily compounded by the halo effect when delivered by a person of perceived statute. Narrative fallacies arise from human’s inevitable continuous attempt to make sense of the world and the fact that “the explanatory stories that people find compelling are simple are concrete rather than abstract… and focus on a few striking events”. The narrative fallacy (a term actually coined by Nassim Taleb) is another pertinent example. ![]() ![]() When people are given a choice between 1) a sure loss of £500 and 2) 50% chance to lose £1,000, the majority will prefer option 2. Loss aversion explains the reason why you will be proportionately more unhappy losing a £50 note than you will be happy finding one (by about two times in fact). The halo effect occurs: “when the handsome and confident speaker bounds onto the stage, you can anticipate that the audience will judge his comments more favourably than he deserves”. If you haven’t already heard of some of these cognitive biases then you’ve certainly experienced them. Kahneman calls these assumptions heuristics and, for entrepreneurs, they can be deadly. An awareness of them is the first step to countering them. We assume certain things automatically without having thought them through carefully. ![]() However, it is prone to engage in a number of fallacies and systematic errors that lead to flawed opinions and adverse decision making, otherwise known as cognitive biases. Kahneman identifies that the human brain works very well most of the time and our judgments are sound. It’s ideas are so potent that they won it’s author Danuel Kahneman a Nobel in economics. Thinking Fast and Slow is a book about biases of intuition.
