We all have opinions and like to express them and the internet makes it much easier for more people to voice their strong points of view. There are many people who are more informed or knowledgable than others but this isn’t a ticket to being right with their opinions. It’s still subjective criticism if it isn’t done in a professional and trained way therefore bias rears its head in most cases resulting in a limiting, single perspective.
Even when the risk of bias was explicitly pointed out to them, people remained confident that they weren’t susceptible to it; indeed, they actually rated their performance as more objective than they’d predicted it would be at the start of the test. “Even when people acknowledge that what they are about to do is biased,” the researchers write, “they still are inclined to see their resulting decisions as objective.”
This is more evidence for the “bias blind spot”, a term which refers to the head-spinning fact that we have a cognitive bias to the effect that we’re uniquely immune to cognitive biases. Take the famous better-than-average effect, or Lake Wobegon effect, whereby the majority of people think they’re above average on any number of measures – their driving skills, their popularity, the quality of their relationship – when clearly they can’t all be right.
