In scientific research, skepticism and rigorous thinking are prerequisites when dealing with collecting and interpreting data as part of research. One needs to keep questioning results and then keep reformulating hypotheses. This is the iterative process that leads to a better understanding of nature.

In daily life however, people are conditioned to not offend others. Many times, one needs to package the truth in ways that are palatable to society. Different individuals respond to such social conditioning in different ways.

There are many individuals who occasionally go against accepted beliefs and tell the truth as it is. Such individuals can often bring about very good changes to society.

Of course, not everyone who criticized should not be under the impression that they have done society a favor. It is the spirit of criticism and the overall results that matter.

On an individual level, one may find that constructive criticism coming from sources of good character is very beneficial.
