This is what I've learned from the research. Basically, to make better decisions 1. one needs to have a lot of data about the thing 2. he/she should define the parameters according to which the procedural instructions will the made in-order to make decision. 3. one should be aware of the cognitive biases while making a decision

For Example- * suppose you are trying to find a college 1. Gather data about the colleges 2. compare the colleges on the parameters you've set 1. like admission fees, companies visiting, average or highest package offered 3. And make sure that you are aware of cognitive biases
