Have you ever wondered how easily you are influenced? In this episode of Wondering About…, we’re diving into the fascinating science of influence. We start with a seemingly innocent Tiktok that led us down the rabbit hole of pharmaceutical reps and gifts to the psychology of reciprocity, familiarity, authority, and social proof. We explore the subtle ways other people can shape what we think, what we choose, and what we do. And here’s the twist: research suggests we’re pretty good at recognizing bias and influence in other people, while being much less likely to recognize it in ourselves. So are we really as independent-minded as we think we are? We’re wondering about drug reps, free lunches, advertising, friendships, social media, and all the invisible nudges happening around us every day. Because maybe the most interesting question isn't “Am I being influenced?” It’s “Who—or what—is influencing me?” Aikin, K. J., O’Donoghue, A. C., Miles, S., DelGreco, M., & Burke, P. (2024).
