The Social Brain

Welcome back! Building on what we’ve already explored—our sensitivity to environmental cues and the evolutionary lens of the "riverbank mind"—this module zooms in on one specific and especially powerful form of environmental influence: other people. While all stimuli shape our attention and behavior to some extent, the influence of other humans is uniquely strong. And we know this to some extent, Aristotle famously said that “man is by nature a social animal” but I think the depth and implications of that fact are often underappreciated. This module is about unpacking just how deeply social forces shape our actions and experience—and how we can use that information to work for us, not against us. For instance, if you’ve ever felt like you cared too much what other people think, and perhaps even reprimanded yourself for it - the material in this module may be helpful. Because the thing is are are wired to care what other people think, even if part of us doesn’t want to! This all makes sense if we go back to the riverbank - social belonging was everything. You could not live alone. You needed others, you needed your tribe for food, for protection, for survival. In other words, to be cast out from the group was to risk death. So our brains adapted. We became incredibly attuned to one another, to be vigilant that we wouldn’t be cast out. This includes things like being sensitive to other people’s tone of voice, or facial expressions, scanning for approval, disapproval, or indifference. Social harmony was super important. And well, of course, the world has changed, but our wiring hasn’t! And this has so many major consequences on our daily lives. For instance, it is not uncommon for many of us to see hundreds of people in a day—this is more than our ancestors might have seen in a lifetime! But our brains don’t know that! They still treat each social cue as meaningful. So this means that a momentary glance of impatience from a barista or a co-worker’s sigh makes a difference! Our brains are picking up on it and it can ripple through our emotions or behavior. Because, back in the riverbank, in a world where every person mattered, no interaction was neutral. If there was a person, your brain was picking up social cues. Automatically. Like your pupils dilating with changes in light. What this boils down to is that our emotional experience—our day-to-day sense of well-being—is deeply dependent on our social experience. We often think of emotions as one thing and relationships as another. But there is so much overlap! People are such a powerful source of our emotional experience. And this is all people - your friends and family, of course, but also the barista and a random co-worker! The people around us affect not just our mood, our motivation, our confidence, so so much. On some level, sure, we kind of know this, but we undersestimate how this works on the micro level, how small changes can have little ripple effects. And what’s important to realize is that the influence of others will impact our behaviour of course as well. As social beings, we want to belong and so the norms of our groups will become our norms to some extent. We imitate, adapt, and adjust—often unconsciously. If you work in a fast-paced, high-status environment, you may start prioritizing certain kinds of accomplishment and recognition—even if that’s not what you value. If your social circle is health-conscious, or entrepreneurial, or deeply spiritual, those norms begin to nudge you without anyone needing to say a word. Now, importantly here I am not about saying anything about whether this influence is good or bad. It just is. But in terms of this program, this is key to keep in mind because the influence of other people, well, it can pull us into living by default—or it can help us live by design. So rather than pretending we’re immune, we can begin to ask better questions: Questions like: Whose influence am I absorbing every day—without realizing it? Are the people around me reinforcing the life I want—or the one I’ve settled into? How can I make the voices and values that matter most to me more present, more visible, and more salient in my everyday life? There’s power in knowing how social we really are. And it gives us one more tool to align our actions with what truly matters. That’s where we’re headed this week. We’ll unpack how other people shape our highs and lows, our habits and values—and how to harness this quietly powerful force to support the life you want to live
