The coin flip, the ultimate 50-50 choice, is actually a little biased. According to a Stanford study, even a fair coin is about 51 per cent likely to land on the same face it started on.

When you've got a weighty decision on your hands, it can be tough to know what to do. Your emotions and biases can get in the way, because you're too close to the situation. To help make your decision, think about how you'd advise a friend.
