It's not a title algorithm, it's a character limit.

Full title, "...than ever": 64 characters

Another title currently on the front page has 74 characters: "The Many Roots of Our Suffering: Reflections on Robert Trivers (1943–2026)"

I stand corrected.

There isn't a technical reason why titles have to be that short, memory isn't in that short supply despite the RAM shortages. A function, therefore an algorithm, is deciding to truncate the title for some reason.

Which you find to be the reasonable explanation over just OP editorializing the title with their own hands because...?

Because the edited title is incoherent and grammatically incorrect.

Until recently that would have marked it as likely done by simplistic automation. These days, it's hard to tell, because humans seem more likely to make simple errors of grammar.

no, as I indicated the full title is within the character limit, to test it I opened up a submit form and it did not say the title was too long.
