Critical Thinking and Decision Making



Critical thinking is thinking that proceeds on the basis of careful evaluation of premises and evidence and comes to conclusions as objectively as possible through the consideration of all pertinent factors and the use of valid procedures from logic (Carter, 1973).

    Decision making in democracies is a process of reaching agreement in group situations through discussion, debate, and analysis. Decision making should be more than the aggregation of performed opinions. Opinions must be confronted with each other in the public sphere, and all participants in this public discourse should truly listen to each otherís arguments. To make proper democratic decisions, no groups should be excluded (Lipset, 1995).

  • To associate is to link people or things together in oneís mind; to connect people or things because they occur together, or because one produces the other.

To illustrate these skills, a teacher might use examples of common problems that get in the way when we try to tell ourselves the truth about the things we are doing and the decisions we are making. Using examples of common problems in critical thinking, like the ones listed below, the teacher might assign the students to play roles in similar situations. Then the teacher could ask them how they would change the situation in a positive way and assign them to play those roles, too.
Common problems in critical thinking that people should avoid (Callahan, 1998):
    • Going too far (overgeneralization)
    • Getting personal
    • "You are another"
    • Cause and effect
    • Making false comparisons
    • Experts
    • Saying things everyone will like
    • Arguing in circles
    • Self-evident truths
    • "Itís either black or white"
    • "If youíre with them you must be Ö"
The following are examples of common problems in critical thinking (Callahan, 1998):
  • Getting personal : Sometimes people try to win an argument by ignoring the issue and attacking the other person. 

"I donít care what he said, heís a jerk, I know it, you know it, everybody knows it, so Iím not paying attention to any of his ideas." 

"Youíre such a wimp, you sound like somebody who canít make up his/her mind. Youíre not one of us; youíre just out to get the kids to like you and youíll do anything it takes; your old man was the same way."

  • Arguing in circles:  Sometimes people use a conclusion to prove itself.

    She must be very smart. She does well on tests. How do we know she is smart? She does very well on tests.
