Anchoring bias – Over reliant on the first piece of info – first info is accurate
Availability heuristic – over estimate importance of info – anecdotal
Bandwagon – protection in numbers – more people believe = true
Blindspot bias – I have no bias
Choice supportive bias – your choice makes you happy even if it is a flawed choice

Information Bias
Ostrich Effect
Clustering Illusion – see patterns in entirely random events – gambling, sports superstitions
Confirmation Bias – Only accept evidence that supports our perspective
Conservatism bias – “We have always done it this way”
Information bias – too much info is not always good – I have cancer, AIDS, and a cold
Ostrich effect – Ignore dangerous/negative info

Pro innovation bias
Recency
Outcome bias – judgement based on the outcome and not how the decision was made (gambling, clean bill of health)
Overconfidence – Too confident about abilities (Darwin Awards)
Placebo effect – It makes me feel better = actual medicine
Pro innovation – Overvaluing usefulness – new and shiny doesn’t mean useful (apps)
Recency – latest info is not necessarily how it is going to be forever. Past studies are useful.

Selective perception – Expectations influence what we see – finding fault in an opposing group & not your own
Stereotyping – Expectations of a group or individual to have specific qualities w/o accurate info
Survivorship bias – basing judgement on surviving examples and not the ones who failed – science
Zero risk bias – Comfort in certainty – eliminate risk even if not productive – medical decisions

News groups can use your bias
Advertisers rely on your bias

13. Cognitive Bias
Everyone has bias. It is really easy to spot other people’s bias, but harder to spot your own. Scientists use instrumentation and peer review to overcome bias. We rely on repeatable data to show us what the truth and facts actually are. Scientists are held to a high standard of honesty for this reason. We have to address our own biases.

14. Cognitive Bias
What do we do to eliminate bias?

15. Cognitive Bias
Some bias is OK!- food preferences, TV etc. Bias oppressing or harming other people is not. Take a look in the mirror. Self awareness is enlightening yourself. Everyone has bias. That doesn’t make us bad people. It makes us human. We have to keep it in check by addressing the bias we have.
