When r is low or r=0, you’re actively harming your genetic kin due to competition.
The resources are no longer in equilibrium between groups, one has the resources of the other.
This is why families encourage loyalty and the state competes with doting teachers.
Every war is actually about competing genetics, even in chimps.
This is about genophilia.
Strangers have high genetic distance, highest for race.
And in couples with a large age gap, within a few years the younger party begins to match the visible age of the elder. It affects facial aging.
Ideal gap is five.
We prefer the thede.
While previous research has suggested that we prefer voices that sound like they are coming from smaller women or bigger men, the new study – published today in the journal PLOS ONE – identifies a variety of other acoustic signals that we find appealing.
“The voice is an amazingly flexible tool that we use to construct our identity,” says lead author Molly Babel, a professor in the Department of Linguistics. “Very few things in our voices are immutable, so we felt that our preferences had to be about more than a person’s shape and size.”
Aside from identifying the overwhelming allure of one’s own regional dialects, the study finds key gender differences. It showed a preference for men who spoke with a shorter average word length, and for “larger” sounding male voices, a finding that supports previous research.
For females, there was also a strong preference for breathier voices – a la Marilyn Monroe – as opposed to the creakier voices of the Kardashians or Ellen Page. The allure of breathiness – which typically results from younger and thinner vocal cords – relates to our cultural obsession with youthfulness and health, the researchers say. A creaky voice might suggest a person has a cold, is tired or smokes regularly.
Babel says the findings indicate that our preference for voices aren’t all about body size and finding a mate, it is also about fitting in to our social groups.
