I\u2019ve been wondering how differently people experience social interaction, and how much or little we seek it. Also whether there\u2019s a pattern in when we need more or less. Because with me it’s changes all the time. <\/p>\n\n\n\n
Some people get energised in a crowd. Others recharge in stillness. And some, like me, need both, just in different amounts.<\/p>\n\n\n\n
Recently I came across an interview with Andrew Huberman<\/a> that explains this in the clearest scientific way.<\/p>\n\n\n\n It\u2019s not really about personality.<\/p>\n\n\n\n It\u2019s not even about introversion or extroversion the way we usually think of them.<\/p>\n\n\n\n It\u2019s about dopamine. And homeostasis.<\/p>\n\n\n\n And it might explain a lot, everything is just so finely tuned. And that\u2019s such a beautiful way to look at it, so I decided to dive deeper.<\/p>\n\n\n\n Social Homeostasis<\/strong><\/p>\n\n\n\n So here\u2019s how Huberman puts it.<\/p>\n\n\n\n Just like your body regulates hunger and thirst, your brain also regulates social interaction through something called social homeostasis.<\/p>\n\n\n\n Your brain has a set-point for how much social input you need to feel good. Not too much. Not too little. Just right.<\/p>\n\n\n\n And when you\u2019re off-balance, for example, you\u2019ve had too little meaningful connection, your brain gives you a gentle push to go seek it. Like it would if you were dehydrated or low on sleep.<\/p>\n\n\n\n But everyone\u2019s set-point is different.<\/p>\n\n\n\n Introverts and Extroverts Aren\u2019t Opposites, They\u2019re Just Calibrated Differently<\/strong><\/p>\n\n\n\n Huberman explains that what we call introverts and extroverts is actually a difference in how efficiently our brains process dopamine, the molecule that makes us feel rewarded and energised.<\/p>\n\n\n\n \u2022 Introvert-types get a strong dopamine hit from a single, meaningful conversation. They fill up fast. They don\u2019t need hours of chatter to feel connected. Their brain might simply hit the jackpot sooner.<\/p>\n\n\n\n \u2022 Extrovert-types metabolise social interaction differently. They get smaller dopamine hits per interaction, so they naturally seek more of it to feel that same satisfaction.<\/p>\n\n\n\n It\u2019s not better or worse. It\u2019s just different brain wiring.<\/p>\n\n\n\n Dopamine Sensitivity and Action Sports<\/strong><\/p>\n\n\n\n Dopamine doesn\u2019t only affect social interaction. It also drives motivation across all types of experience, especially in high-intensity activities.<\/p>\n\n\n\n At the heart of it is dopamine, the signal for pleasure, motivation and that internal \u201cyes, do that again\u201d response.<\/p>\n\n\n\n But not all brains respond to dopamine in the same way.<\/p>\n\n\n\n Some people have what scientists call lower dopamine receptor sensitivity. You could say their reward dial is turned down. They need bigger hits to feel that spark. These are often the people drawn to action sports, kitesurfing, cliff diving, skateboarding, intense activities that flood the system with dopamine and adrenaline. Their brain\u2019s sweet spot is only reached through strong stimulation.<\/p>\n\n\n\n What Happens on a ‘No-Wind Day<\/strong>‘<\/p>\n\n\n\n But what happens on a day with ‘no wind or no waves’?<\/p>\n\n\n\n The dopamine dial still wants that buzz. So the brain may go looking for something else, like social connection, novelty or challenge, to reach its baseline reward state.<\/p>\n\n\n\n
