Answer: informational social influence
Step-by-step explanation:
If we need to make a decision we need to have a source of information that can assist us. Sometimes we we ask from people with expertise in that issue or we conform to what else is doing assuming that they know what we don't know. Sometimes we may study the behavior of other people who may be facing the same situation like ours and see how are they doing things so that we can know how to behave also this is known as informational social influence. In this case we follow the lead of others in order to know what to do. You see and use information from your social environment around you.
social reviews is also one way of leading to make a decision through social information influence.
