문제 내용: One of the tricks our mind plays is to highlight evidence which confirms what we already believe. If we hear gossip about a rival, we tend to think "I knew he was a nasty piece of work"; if we hear the same about our best friend, we're more likely to say "that's just a rumour." Once you learn about this mental habit called confirmation bias-you start seeing it everywhere. This matters when we want to make better decisions. Confirmation bias is OK as long as we're right, but all too often we're wrong, and we only pay attention to the deciding evidence when it's too late. How
선택지 1: we make our rivals believe us
선택지 2: our blind spot helps us make better decisions
선택지 3: we can protect our decisions from confirmation bias
선택지 4: we develop exactly the same bias
