When one avoids an honest, deliberate and comprehensive approach to a matter because it may introduce an adverse effect on personally and professionally held views and beliefs.
Intellectual dishonesty is a failure to apply standards of rational evaluation that one is aware of, usually in a self-serving fashion. If one judges others more critically than oneself, that is intellectually dishonest. If one deflects criticism of a friend or ally simply because they are a friend or ally, that is intellectually dishonest. etc.
Aka, hypocrisy is the short version.
