Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
longer ring finger relative to pointer finger = lower D2:D4 ratio; higher prenatal androgen exposure.

In people that self-report as lesbians also tend to have a smaller D2 to D4 ratio. So this is consistent with the auto acoustic emission study that Dennis McFadden had published.

And in females because they're exposed to less androgen in utero typically. Then those fingers tend to be more equal in length.
