Document Summary
Psych 105: individual and social behaviour (28th january 2019)- lecture 10. Availability bias relaying too strongly information that is easily accessible. Most people will say first, because it is more difficult to come up with words whose third letter is d. there are more words those third letter is d". Percentage of people who die from various causes overestimate causes that are common (murders, terrorist attacks, plane crashes) and get more attention in media, and underestimate mundane causes like heart attacks. Doctor"s office misdiagnosis is possible due to availability bias; doctors are predisposed to think new patient has same disease if symptoms are like the disease, they have been treating a lot. Confirmation bias trying to confirm the hypothesis, and not accounting for any counter evidence that can disconfirm the hypothesis. It is possible to disprove a hypothesis, but a hypothesis can never be proven. A strong hypothesis is the one that stood up to many attempts at disproving.
