To dismiss one’s instincts is irrational. Our bodies developed fine-tuned monitoring and alerting systems (our instincts). To ignore your gut is to ignore your hard-earned experience.
Trust your gut. The scientific reason for why it’s telling you that will be explained later.
Usually that's good advice :-)
In other cases, some people got bullied as children or grew up with a weird parent, and because of that feel in their gut, their intuition tells them,
that no one likes them, and they better stay at home and avoid people. Then, trusting one's gut or intuition, can damage a whole life.
What you call "the guts" and intuition and feelings, can learn the wrong things, during childhood. Can be good to apply some logical reasoning, and also talk with other people if it's something important
However, I think you underestimate the brain thinking that the anti-vaxxers are making—-believe me, they have done hardheaded rationalization of their beliefs.
Egg-headed decisions come from bad brain thinking, not from trusting your gut.
Ask the grunts/troops/anyone who is actually writing code: how do you really feel? Most feel in their gut things got too complex and bad decisions are being made.
If these engineers only actually listened to their gut, they would be pushing back hard to get complexity reigned in, to get back to a much cleaner architecture. But for a myriad of reasons, such as not wanting to appear clueless in a fast changing tech world, the engineers stay silent.
The rationalization is a very brain activity.
Do a reality check on yourself. What feels have you been rationalizing or dismissing? Take a look by observing—what kind of feeling is it? Where is it in your body? (A lump in your throat, tightness in your stomach?) Observe what it is. Don’t explain it away or it will stop being observable.
Once you observe, you will learn new information, which will then inform your subsequent decisions.
This is very different from the scenarios mentioned by the GP, where people who are not experienced in the technical field (i.e. not immunologists or HVAC engineer, respectively) ignore the advice of people who are experts, just because it feels right to them in their gut.
I would say, listen to experts (and not your gut) when outside of your field, and listen to your gut (but not only your gut) when in your field.
But that’s besides the point—-learning to trust expert advice is a brain behavior that has to be properly learned. (For example, many of us have learned to catastrophize and over-generalize, where bad advice from one expert suddenly translates into not listening to all future experts).
I’m imploring: do not dismiss your gut, folks! Please continue to use brain, but stop dismissing your gut.

“I think therefore I am” is oversimplified bunk.

And thinking your gut knows something is part of those biases, namely, confirmation and selection bias.
Or, it's System 1, the fast system. While your System 1 might make bias mistakes, I believe it can be trained not to make them.
Disagree. Even my gut says to not vaccinate my attic.
