Answer:
heuristics
Explanation:
A heuristic approach to problem solving employs a practical method, or rule of thumb, that is not optimal nor it tries to guarantee perfection, but is sufficiently good to serve for practical purposes specially when time is limited.
Micah's approach may not guarantee that the people that he chooses will be the adequate ones, but he considers his method to be close enough to a correct solution and it is also very simple and easy to carry out.
