A brief guide to critical thinking

Raymond S. Nickerson (1987), an authority on critical thinking, characterizes a good critical thinker in terms of knowledge, abilities, attitudes, and habitual ways of behaving. Here are some of the characteristics of such a thinker:
1- uses evidence skillfully and impartially

2- organizes thoughts and articulates them concisely and coherently

3- distinguishes between logically valid and invalid inferences

4- suspends judgment in the absence of sufficient evidence to support a decision

5- understands the difference between reasoning and rationalizing

6- attempts to anticipate the probable consequences of alternative actions

7- understands the idea of degrees of belief

8- sees similarities and analogies that are not superficially apparent

9- can learn independently and has an abiding interest in doing so

10- applies problem-solving techniques in domains other than those in which learned

11- can structure informally represented problems in such a way that formal techniques, such as mathematics, can be used to solve them

12- can strip a verbal argument of irrelevancies and phrase it in its essential terms

13- habitually questions one's own views and attempts to understand both the assumptions that are critical to those views and the implications of the views

14- is sensitive to the difference between the validity of a belief and the intensity with which it is held

15- is aware of the fact that one's understanding is always limited, often much more so than would be apparent to one with a noninquiring attitude

16- recognizes the fallibility of one's own opinions, the probability of bias in those opinions, and the danger of weighting evidence according to personal preferences
