Let’s try again then. I will happily accept the criticism, because it is a common one, that I presume more of the audience’s capacity for association than I should and therefore don’t explicitly draw the arguments as clearly as I should.

Research indicates a correlation between shorter gestation (preterm birth) and an increased likelihood of left-handedness. This correlation is not typically discussed in terms of “political correctness” but rather is based on observed data from various studies. Here’s a more detailed breakdown:

Correlation Between Shorter Gestation and Left-Handedness:

Research Findings: Multiple studies have found that children born prematurely (before the standard 37-week gestation period) are more likely to be left-handed than those born at full term.

The underlying reasons for this correlation are still being studied, but it is hypothesized that shorter gestation may affect brain development in ways that increase the likelihood of left-handedness. Premature birth can influence neurodevelopment, possibly leading to variations in brain lateralization.

Possible Explanations:
Neurological Development: The development of handedness is related to brain lateralization, which may be influenced by the conditions in utero. Premature birth might disrupt or alter the usual processes of brain lateralization, leading to a higher incidence of left-handedness.

Perinatal Factors: Other perinatal factors associated with preterm birth, such as lower birth weight or complications during delivery, could also contribute to the development of left-handedness.

Statistical Association: The association between shorter gestation and left-handedness has been observed in multiple populations, suggesting that this is a consistent, though not absolute, finding. It’s important to note that not all preterm births result in left-handedness, but the likelihood is statistically higher compared to full-term births.

IOW:
(Early: left handedness < mixed handedness) > (Timely:(heavily biased right handedness)).

I should also note that other issues emerge with excess gestation, thought the findings are mixed and I’m skeptical of most of them.

Cheers
