Voluntary decisions require analyzing the situation, goals, and people involved by examining all available information. Involuntary actions are reflexes and habits learned through repetition without much thought. Hidden persuasion can influence decisions through visual stimuli, accelerated speech, embedded images, and subtle suggestions. Voluntary thinking allows influence from credible sources, authority figures, peers, and group thinking, as well as interpersonal needs, but requires examining available information. Group think seeks harmony over individual ideas, prioritizing affection, inclusion, and control. Probability of success or failure due to time, place, people involved affects whether one follows through on a decision.
