Source characteristics, including credibility and attractiveness, play a vital role in influencing attitude change. Attitudes are more likely to undergo a transformation when the message is delivered by a highly credible source rather than a source with low credibility. To illustrate, consider adults who are in the market for a new laptop. They are more likely to be persuaded by a computer engineer who highlights the unique features of a specific brand of laptop, compared to a schoolchild who provides the same information. However, if the buyers themselves are schoolchildren, they may be more convinced by another schoolchild endorsing a laptop rather than a professional offering the same information. This highlights the importance of relatability and peer influence in shaping attitudes within a specific age group.
