  • S. Luoto

    Frontiers in Psychology
  • 2021
Psychological sex differences have been studied scientifically for more than a century, yet linguists still debate about the existence, magnitude, and causes of such differences in language use.…
Birth Order and Sibling Sex Ratio in Androphilic Males and Gynephilic Females Diagnosed With Gender Dysphoria From Iran.
TLDR
The fraternal birth order effect that was found for the transgender androphilic males, similar to that found in gay men, suggests a common underlying causal mechanism and generalizability for the study of birth order and sibling sex ratio that has been restricted to Western samples of adults diagnosed with gender dysphoria.

TLDR
The fraternal birth order effect is the tendency for older brothers to increase the odds of homosexuality in later-born males and in homosexual subjects with masculine versus feminine gender identities is compared and evidence for the reliability of the effect was consistent.
Psychology's Renaissance
TLDR
It is shown that the scientific practices of experimental psychologists have improved dramatically and is argued that meta‐analytical thinking increases the prevalence of false positives.
Feeling the future: A meta-analysis of 90 experiments on the anomalous anticipation of random future events
TLDR
A meta-analysis of 90 experiments from 33 laboratories in 14 countries which yielded an overall effect greater than 6 sigma is reported, indicating that the database is not significantly compromised by either selection bias or by intense “ p-hacking”—the selective suppression of findings or analyses that failed to yield statistical significance.
False-Positive Psychology
TLDR
It is shown that despite empirical psychologists’ nominal endorsement of a low rate of false-positive findings, flexibility in data collection, analysis, and reporting dramatically increases actual false- positive rates, and a simple, low-cost, and straightforwardly effective disclosure-based solution is suggested.
Introduction to Meta-Analysis
Birth Order, Sibling Sex Ratio, Handedness, and Sexual Orientation of Male and Female Participants in a BBC Internet Research Project
TLDR
The results yielded some evidence confirming prior findings that non-right-handedness is associated with homosexuality in men and women, that older brothers increase the odds of homosexuals in men, and that the effect of older brothers on sexual orientation is limited to right-handed men.
Childhood Family Correlates of Heterosexual and Homosexual Marriages: A National Cohort Study of Two Million Danes
TLDR
This study provides population-based, prospective evidence that childhood family experiences are important determinants of heterosexual and homosexual marriage decisions in adulthood.
Interaction of fraternal birth order and handedness in the development of male homosexuality
TLDR
Evidence is found for an interaction between two of the best established etiologic factors in the literature on male homosexuality: fraternal birth order and hand preference and the number of non-right-handed homosexuals with older brothers is smaller than expected.
Why Most Published Research Findings Are False
TLDR
Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true.
