Bias

Bias is the scourge of Human-kind; whether it's confirmation bias, survivorship bias, the bandwagon effect, ingroup bias or even the gamblers fallacy, bias invariably leads us into making bad decisions. From people who believe they were cured by sugar pills (confirmation bias) through to people who voted for Trump (bandwagon) we are all influenced by bias from some perspective or other. The challenge is to recognise that fact and to be able to step (intellectually) outside of our personal bubbles for a bit so that we can look at a situation objectively, in my experience, far more enlightenment tends to come that way.
