text: An opinion that is repeated a bunch of times between people is great for decision making because the person asking for advice will know that it's the answer. How they'll know is because if it's repeated more than twice, it means that would be what their friends would do if they were in that person's situation. For example, Generic-Name went to go ask his friends Generic-Name, Generic-Name, and Generic-Name what he should get his teacher for her birthday. Generic-Name said to get her a nice card, Generic-Name said to get her a coffee mug, and Generic-Name said to get her a drinking cup/bottle. Generic-Name should go with Generic-Name and Generic-Name's ideas because they are both pretty similar. Going with the same type of ideas are for the best interest for the problem.
