I would have written the headline as "In an Absolute State: Elevated Use of Absolutist Words Could Be a Marker Specific to Anxiety, Depression, and Suicidal Ideation" but maybe that's only because I'm in a good mood.
That's a better title than my submission but sadly over the limit for HN titles.
I started with the original title of "In an Absolute State: Elevated Use of Absolutist Words Is a Marker Specific to Anxiety, Depression, and Suicidal Ideation" and cut words until it fit.
