Summary
Learn how to tap into your “gut feeling,” which knows more than you think it does; and why Earth's core is growing lopsided.

| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from |
| 0:05.2 | Curiosity.com. I'm Cody Gough. And I'm Ashley Hamer. Today you learn about the |
| 0:09.8 | scientific explanation for your gut feeling and why it knows more than you think and why Earth's core is growing lopsided |
| 0:17.6 | Let's satisfy some curiosity |
| 0:20.8 | It might seem like a bad idea to go with your gut sometimes. I mean what is your |
| 0:26.8 | gut no anyway? Your gut's not your brain? Well that gut feeling has a scientific name, and according to research, it knows more than you think it does. |
| 0:38.0 | So in 1992, a neuroscientist ran an experiment where he had participants watch a target |
| 0:44.8 | disappear and reappear on a screen. They did this over and over again for a few hours. |
| 0:51.6 | What the participants didn't know was that the targets were |
| 0:54.6 | following a predictable pattern but it was a really complicated pattern and after a |
| 1:00.5 | while the participants began to accurately predict where the target would appear next. |
| 1:06.0 | But here's the thing. They couldn't explain how they knew. |
| 1:10.0 | Even when they were offered $100 to identify the pattern, they couldn't do it. |
| 1:16.1 | Pavolu Wiki was the neuroscientists who ran that experiment. |
| 1:19.8 | He called the phenomenon non-conscious information acquisition. |
| 1:24.8 | Basically, we have the ability to sense, store, and recall information completely unconsciously. This phenomenon is governed by something called interoception. |
| 1:36.5 | That refers to an awareness of the inner state of the body, |
| 1:40.3 | things like |
| 1:44.7 | sight or smell, but much more subtle. |
| 1:48.3 | Just like sight and smell involved sensors that pass information to the brain, sensors all over your body pass information |
| 1:56.0 | to a brain structure called the insula, which is a region embedded within this cerebral cortex. |
| 2:03.0 | These sensors might not be giving our conscious minds |
