Based on the image above, we can see that there are two men in the gym with the same purpose that is working out or training their muscles this can be related to the social behavior representative heuristic which carries the meaning of judgment based on similarity, because we can observe that they are carrying weights in their hands. Next, we can see the difference of body shapes between the two men in this photo we can quickly assume that the man in the grey singlet has been working out more than the man in the white singlet just because of the body shape , we can relate this to the social behavior schema because of self-fulfilling predictions in a sense, make themselves come true (also known as self-confirming effects). Moving on, As we observe the muscles of the man wearing the grey singlet , his muscles are big and strong. For all we know he could possibly be steroids because we don’t know how long has it been since he started working out to build such big muscles, this can be related to the social behavior avaibility heuristics with means judgment based on easy access of specific kinds of information.
