Why Do Some People Hate the Sounds of 'Screeching' Elastics?

AI Thread Summary
A significant portion of the human population experiences irritation from specific high-pitched sounds, such as the screeching of elastics or children's fingers rubbing against a balloon. Individuals generally fall into two categories: those who find these sounds intolerable and those who are unaffected. Research suggests that children may be more resistant to these noises, potentially due to differences in ear structure or sensitivity that change with age. The irritating sounds often share frequencies with those of a crying baby or a human scream, which are linked to survival instincts. This sensitivity may enhance the likelihood of responding to distress signals, ultimately benefiting the survival of vulnerable individuals like infants.

What causes a good proportion of the human population (including myself) to be irritated by the sounds of 'screeching' elastics? Such as that of childrens' fingers rubbing against a balloon.
It seems that we are sorted into 2 categories, either you hate the sounds, or they don't bother you whatsoever. Children seem to be more resistant to the sounds as well. Does this have something to do with our ear structures, possibly as you grow older the inner ear changes in a way that makes you susceptible to falling into the 'hate it' category?

Overall, research shows that this ear-splitting noise has the same frequency as that of a crying baby and a human scream, indicating that these sounds are tied to survival. For instance, people attuned to these frequencies may rescue a crying infant sooner, improving the baby's longevity.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
