Most of people are not thinking, but reacting and following a series of responses that they’ve either been told or learned. The people sometimes can be on autopilot, but they better know how to switch it off.
Critical thinking is simply being as objective as we can in analyzing and evaluating an issue or situation, so that we can form an unbiased judgement.
Stop acting on emotions. Beeing faced with problems every day when working on a pro-ject make your decisions to be impartial. The only thing guiding the decision should be what’s best for the project.
