This is a type of learning called habituation. Learning about new dangers is beneficial to a new organism or tribe. But once you have to start triaging which dangers to care about, you eventually have to set a threshold for what can even take your attention. And in a world with a vanishingly small attention budget, this is everything. So your response is natural and correct, a fundamental approach to dealing with a problem of this scale. But we have to ask ourselves, is this something we want to habituate ourselves to? Are we placing too much emphasis on reducing energy costs for the individual mind vs the tribe's best interests? One way or another, it's a sign of the times. We only feel the need to habituate to these signals because they're becoming background noise to even larger problems. https://en.wikipedia.org/wiki/Learning#Habituation https://en.wikipedia.org/wiki/Learning#Habituation
