Oh, hey, it's your sister's high school friend who is eating frozen custard in the background of a hometown date on the bachelor.

Not really. Alli Wart back with an episode. You're gonna hate. Maybe I dare you to listen.

It is packed with bananas information about the human mind and psyche and about fear and power and social contagions and delightful squeals, but it is absolutely not soothing whatsoever.

Don't fall asleep to this. Don't play this with your grandpa recovering from surgery on the couch next to you. Don't turn to me if you're having anxiety about your colonoscopy prep. Not the episode.

Not the episode for that at all. This one is gonna tear at the fabric of your sanity and thisologist offers so much cocktail party trivia.

So he did his undergrad in animal behavior and got a master's in psychology and a PhD in zoology a postdoc with primates at Rockefeller University and is now a professor in the Department of Psychology at Emory where he has been since 1984.

And if you have seen an article about the study of human screams, it is likely that this person has been quoted.

So here we go. But first, thank you to all the patrons who submitted wonderful questions for this. You can join the Patreon at patreon.com slash allergies for a buck a month and submit questions. Also thanks for spreading the word about the show, telling friends and leaving reviews, which helps so much.

This one this week, holy shit. So worth it. I'm gonna put the review at the end of the episode as the secret. I want to read the whole thing. Anyway, on to screamology.

So the word scream, it said to come from a Scandinavian term, meaning to terrify or cry aloud. So vocalization via forced air and the term screamology was coined in the press years ago about this guy.

So I reached out. Luckily, we had some help in booking him. We talked before the holidays on a day when Emory was having some giant fundraising drive on campus. But luckily, his office appeared to be soundproofed.

So we warmed up our voices and chatted about movie screams, which animals scream the difference between yelling versus screaming, happy screaming, scream queens, scream kings, the decibels and distance of screams screaming in your nightmares, boy bands, dictators, death metal and more with plenty of examples in here that we try to keep quiet, but they're in there.

So get ready with primatologist, research psychologist and one of the world's very few professional dedicated screamologists, Dr. Harold, Gzulis.

Once again, that name is Harold, Gzulis. Gzulis, it's a Greek name three syllables. So pretty simple for a Greek name. And he, him kind of like someone who's been a victim of a Kuzuzufd and is now.

Hi, Ali. Hi, you sound great. Well, let's let's hope I was almost at heart attack coming down here. I mean, Atlanta traffic is notorious and Friday afternoon is the worst and it just turned out to be one of those worst case scenarios.

Oh, no.

And I was rushing to get down here and managed. And then I discovered that the campus is a very noisy place today because Emory, my university is kicking off their big campus.

Big capital campaign. And so this music playing everywhere. Now, fortunately, my office seems to be tucked away just sufficiently well. So it's not really noticeable. I don't know if you can hear anything in the background.

No, I can't at all.

Okay, good. Good.

Now, is, does your office have to be well insulated in case there are screams? Or is it just?

Well, my lab is more isolated. And yet the story goes that people walk by and will hear some of the screams that we're listening to and talking about within the lab and with my students and wondering what's going on.
