If there is an in person interview that you get to, this wouldn't be a bad thing to mention. Make it a casual aside like 'btw, your online application lists phrenology as a possible skill to check and this was a long debunked and very racist pseudo science from the turn of the 20th century, I think someone just copies and pasted a list, but it's essentially having 'race science' as a skill in your application, figured it's something you'd want to be aware of.". Unless you're applying for a racism factory you just did them a solid and pointed out an oversight during the job interview. That should help you, pointing out phrenology is on their application isn't 'don't hire this person cause they're a cage rattler' kinda thing to point out, it's borderline illegal, super mainstream level considered bad and easy to fix (most importantly). You can use this to your advantage
