Understanding why you are anxious in new situations

- [Narrator] Blink number one. Our biological and cultural evolution predisposes us to be alert and anxious in new situations. We all have to be the newbie at some point. We change jobs, change residence, sign up for new classes and so on. But no matter how often we're the new person in the room, most of us feel anxious about it and for good reason. Throughout our biological and cultural evolution we came to naturally fear the unknown. In prehistoric times, we didn't meet many new people. According to evolutionary biologist, Robin Dunbar, it was normal back then to interact with only around 150 other people, and to encounter no more than 300 or 400 others in a lifetime. If we happened to meet strangers or enter unknown territory it made more sense to be anxious and aggressive as it was unclear whether one would be stolen from or even killed. There was no evolutionary incentive whatsoever to remain calm in new situations. According to experts on child development, we've retained this fear of strangers. Infants, for instance, begin to show anxiety around unfamiliar people at six months of age. This feeling is then reinforced by parents and teachers who constantly warn their children against talking to strangers. At the same time, however, we have a fear of being excluded from groups. For more social species, like humans, there are powerful incentives to be part of a group as exclusion can be dangerous. For example, when male monkeys are pushed out of their birth group and into the world, half of them will either be killed or die of starvation before they're able to find a new group. These days belonging to a group isn't crucial to survival, but we still tend to long for inclusion. Modern culture fuels this by stating that only losers are incapable of finding a community. So we feel anxious in new situations and yet still want to fit in. How to solve this paradox?
