What They Said

“It's almost like you are exposing yourself to something that is dangerous, but not really dangerous, right? So it's like a roller coaster ride.” — Cynthia Graber, Gastropod

Gastropod co-host Cynthia Graber, drawing on sensation-seeking research to explain why people deliberately eat extremely spicy chili peppers despite the pain. The comparison is to controlled, survivable thrill-seeking rather than actual risk.

Get to a garbage.

Okay, but a weary weary was already too hot to even taste the flavor for me. Why on earth are people setting their mouths on fire with a million Scoville pepper? Why would you even want to do that?

Cynthia Graber

This is an area of research where people have looked at the degree to which people who like capsaicin in large amounts have a tendency to be sensation seekers. It's almost like you are exposing yourself to something that is dangerous, but not really dangerous, right? So it's like a roller coaster ride. If you assume that they've maintained the roller coaster properly, it's going to be scary, but you're pretty sure that you're going to come out okay on the other end. It's the same thing with capsaicin. It's sort of triggering the brain into, I'm doing something dangerous here. And then you have this post-danger euphoria from having survived the experience with nothing more than maybe a little bit of soreness on your tongue.

Unsurprisingly to me, chili competitions tend to be a kind of chest-beating macho type thing, not my speed. Plus, it's not all fun and games. One guy who ate ghost pepper puree at a contest in 2016 ended up in hospital with an inch-long tear in his esophagus from the irritation. The doctors who treated him said it was because of all the post-chili vomiting. Another reason to skip the chili head competition. But unfortunately, Nikki and I had our own tasting to do, and the weary weary we tried wasn't the hottest. The Carolina Reaper is considered the hottest pepper available today. It's about a million and a half Scoville units. And as you listeners already know, I bought two jars from a local store and I shipped one to Nikki. Are
