Before
Robin Dunbar was trying to discover why animals spend so much time grooming, but instead found how the size of a portion of your brain can affect someone socially. The rule of three is what she found. Maria Konnikova said that “The Dunbar number is actually a series of them. The best known, a hundred and fifty, is the number of people we call casual friends.” This means the average person has 150 people that they may talk to, but are not close friends, then, as you go to a smaller portion of your friends, you consider them closer friends. In the essay, it says that 50 is the number of people that you call close friends and 5 is the number of people you call your close support group.

Robin Dunbar was trying to discover why animals spent a lot of time grooming, but she really found how the size of part of your brain can affect someone socially. She found something she called the rule of three. Maria Konnikova said that “The Dunbar number is actually a series of them.

In the essay, it says that 50 people is the number of people that you call closer friends and there are only 5 people at a time who are in your close support group. This number can change from day to day though. It could be 5 family members, one day and 5 different people the next day.

I changed this paragraph making it more clear by changing the wording of some sentences. I also added to the paragraph adding more detail to the close support group part.
