Final answer:
Expertise is not always a sufficient guarantee that followers will believe and follow a leader's argument.
Step-by-step explanation:
The statement that expertise is typically a sufficient guarantee that followers will believe a leader's argument and follow their influence is False. While expertise can certainly enhance a leader's credibility, there are other factors that can influence whether followers believe and follow a leader. For example, informational social influence is more likely when the answer is unclear and the group has expertise. This means that followers are more likely to be influenced by a leader's argument if they trust the leader's knowledge and perceive the situation as ambiguous.
