Some scholars claim that the theory of planned behavior is based on cognitive processing, and they have criticized the theory on those grounds. More recently, some scholars criticize the theory because it ignores one's needs prior to engaging in a certain action, needs that would affect behavior regardless of expressed attitudes. For example, a person might have a very positive attitude towards beefsteak and yet not order a beefsteak because she is not hungry. Or, a person might have a very negative attitude towards drinking and little intention to drink and yet engage in drinking because he is seeking group membership.
