Which term best describes the act of shunning the truth?

The act of shunning the truth is best described by the term "dissemble." When someone dissembles, they intentionally hide or distort the truth, often to mislead others. This behavior involves creating a false appearance or pretending that one is not experiencing certain feelings or thoughts. It captures the essence of evasion and deception, which is precisely what shunning the truth entails.

In contrast, "conceal" refers to hiding something, but it does not necessarily imply the intention to mislead or distort the truth. "Clarify" is the act of making something clear or understandable, which is the opposite of shunning the truth. "Express" involves conveying thoughts or feelings openly and honestly, which also contradicts the notion of avoiding or shunning the truth. Therefore, "dissemble" is the most appropriate choice for describing this particular behavior.
