The more choices we have, the less likely we are to be content with our decision.

Even if our ultimate decision is clearly correct, when faced with many choices, we are less likely to be happy with what we choose. Because a wealth of choices makes finding contentment that much harder.

The more people who see someone in need, the less likely that person is to receive help.

Researchers call it a “confusion of responsibility,” where individuals feel less responsibility for the outcome of an event when others are around. In fact, the probability of help is inversely related to the number of people present. 

Your mistakes are not noticed as much as you think.

People aren’t paying attention at our moments of failure nearly as much as we think. The perception of our being under constant scrutiny is merely in our minds.

People place too much importance on one aspect of an event and fail to recognize other factors.

To combat this effect, it is important to remember to keep perspective, look at problems from many angles, and weigh several factors before making a decision.
