Commandism is telling the masses what to do expecting that they already have the ideological understanding that you do, which causes people to become confused, question the effort of the organization, and feel left out. Tailism is the opposite - expecting that the masses are not as ideologically convicted as they actually are and failing to lead them to the next conclusion, causing friction and again the feeling that the organization is leaving them out or worse is backwards/not attentive to the concerns of the masses. An organization should lead the masses, include them in party organizing, continue their revolutionary education, and work effectively with them to build revolution. My interpretation
