The other night on the podcast, I asked whether there is an advantage to having a bleak outlook on the future. I believe that there have been some historical advantages to having a negative outlook, but that the advantage has been variable throughout human evolution –sometimes you get a boost from being a pessimist, sometimes from being an optimist. But seeing as life was riskier in the short term for our ancestors, the more risk-averse pessimistic outlook took hold. We developed a natural fear of the future not too unlike our natural fear of the other.
In an evolutionary context, fear of the other is not necessarily a bad thing. If we’re talking about Homo Sapiens vs. Neanderthals or (earlier on) mammals vs. reptiles, an innate revulsion to the threatening other served to keep evolution moving in the right direction. Back then. Today, we need our fear of the other a lot less than we used to. I think it kicks in correctly if, say, you come home and find a stranger in your bedroom. But a “fear” of other cultures, races, religions, lifestyle choices, etc. is not helpful, notwithstanding the fact that major cultural artifacts, lets call them memeplexes, have been developed around this fear. These we know as xenophobia, ethnocentrism, racism, and other delights.
Today we recognize that basic animal instinct as one that we need to control, and the memeplexes that developed around it as not only unhelpful, but morally wrong. What, then, about that closely related animal instinct, our natural fear of the future? Again, it was a fairly useful guide back in the days when human life was one unbroken chain of existential threats. Back when we needed to find prey or starve, avoid predators or be eaten, stay out of the flood plain or drown, keep warm at night or freeze to death, and so on, a healthy fixation on everything that could go wrong and an expectation that many such things would go wrong was key to survival.
