help me solve this puzzle

Theres an attachement below. The game that we are going to play will play with human behavior when given the choice of altruism or self benefit. The scenario is, you and one other person will be left in a room. Sort of like the 'prisoner dilema', you each have to convince the other person to do a certain choice. If both of you agree to work together, each will be rewarded a moderate amount of points, but if one person decided to betray(backstab), one of you will earn the maximum amount of points

To put into context the important of points, the full 200 will be the equivalent of getting bailed out of death row, while 100, 50, and 1 will shorten your sentence in accordance to how many points you get. So its in the best interest for both people to earn the 200, but its a huge risk of 66 percent elimination rate.

What I want you to figure out, is the most likely choice of the other particpant, if YOU decide to not talk at all. That means leaving the other person to his own device, his own choice, and his own thoughts. What would that person most likely do, is the dilemna of this puzzle.

Give me a reasonable and logical explanation, preferably with evidence from text, and I'll award you depending on how well you think you did. Starting from 15 dollars and going from there.
