Thinking Statistically Quotes

“the best system is probably one that involves encouraging negative feedback in person: finding subordinates you trust and asking them what other people complain about most; encouraging a “Devil’s Advocate” mentality during projects and meetings; or asking subordinates what the least-best thing about a particular project is (“yes I know you think this project is wonderful. But if you were to think it wasn’t wonderful, what would you think wasn’t wonderful about it?”) Ultimately, your biggest strengths will be your simple awareness that negative feedback must exist in your organisation, and your determination to keep looking for it despite the psychological temptation for positives to be reinforced.”
― Uri Bram, Thinking Statistically

“many instances of supervisory madness are not the result of malice or idiocy, but rather genuine unawareness due to impeded data-flows (and resultant sample selection bias).”

“Selection Bias: basically, that your inferences will be biased if you use a non-random sample and pretend that it’s random.”
― Uri Bram, Thinking Statistically
