Honesty about one's future conduct, loyalties, or commitments is called accountability, reliability, dependability, or conscientiousness.
"[3] Tolstoy thought that honesty was revolutionary: “No feats of heroism are needed to achieve the greatest and most important changes in the existence of humanity.... it is only needful that each individual should say what he really feels or thinks, or at least that he should not say what he does not think.”[4] Aleksandr Solzhenitsyn ("Live Not By Lies," 1974) and Václav Havel (The Power of the Powerless, 1978) agreed.
“[E]very intelligent, active, and free being should so behave himself, as by no act to contradict truth; ...treat every thing as being what it is.” All else would follow from that.
This concern manifests in political correctness, with individuals refraining from expressing their true opinions due to a general societal condemnation of such views.
Research also found that honesty can lead to interpersonal harm because people avoid information about how their honest behavior affects others.
