text: Why do multiple people's advice help? What if I only want one solution, and I know someone who is qualified to help me and knows a lot about my very important decision? An example as to why more heads are better than one is shown by a test that had twenty people guess the number of marbles in a big jar. Half of the people missed because they either guessed way too high or way too low. The numbers were then averaged, and the resulting number was within about twenty of the actual number of marbles in the jar! This can be applied to asking advice as well. Some people will give horrible advice. That's a fact. But if you look at other people's advice, you are more likely to see that it is bad, and go with the ones that seem great. However, if some people give bad advice, and others give really great advice that you don't want to follow, you can meet in the middle and find a great solution for you. You could also brainstorm ideas and solutions with a group, and just by mentioning a word or phrase, get someone to give great advice that you would never have thought of!
