I used to support the idea of capital punishment. If someone was found guilty of something so bad that it was ever suggested, why SHOULD the state provide food and shelter to such an awful person? Then it was pointed out how expensive it is to keep someone on death row and if the goal of incarceration really is punishment, then shortening the number of days they spend locked up with their demons is really more a mercy than a punishment.

As I've said before, keeping an open mind is all very well but it's a bit like keeping an open skip (dumpster in the US) outside your home - you've got to keep an eye on it, or people will dump all sorts of shit in it.

Typically I find non-believers more open minded. The label applied to us by believers is just completely inaccurate but supports the narrative they would like to put out there.
I find my opinions evolve with more information and possibly change completely if I see where I went wrong. Not often but it does happen

Being skeptical wasnt always my default position, so I think there are far more instances where I changed my mind to the skeptical side with great effort, which coming from indoctrination required an explosively opened mind to achieve. This was aided by shamanic practices such as: psychedelics, meditation, yoga, group music, extreme heat and cold therapies. All those things Im no longer skeptical of and have experienced the benefits of first hand.

The most specific example I can think of that proved true for me is this yogic principle that sounds like total new age woowoo bullshit, but: Im confident that emotional trauma gets stored in our muscles, and stretching can be an emotional regression therapy as much as physical. Particularly the hip flexors, called psoas or “fight or flight” muscles. Ive released tensions there that brought back suppressed memories from preschool about where my procrastination and fear of attention came from. I felt 50lbs lighter suddenly n let go of major leg and back tension I had been holding onto practically my whole life.

Yes. I actually used to think global warming was just a political scare. I even had a professor who pushed that view. Once I started learning that the beliefs I held were based upon faulty evidence and assumptions I corrected them. I now fully accept the scientific consensus that it is real and man made.

I am always willing to listen to someone's arguments, rationalizations, or view points, and am willing to discuss. They usually are the ones who change their stance.

Yes, I was skeptical of Evolution until DNA was demonstrated and it became clear to me how it happened.

Not yet. However, present me with credible, verifiable evidence, and a reasonable
argument, and I might be persuaded to reconsider whatever position I may be holding.
I'm a reasonable person. It's not like I believe in gods or anything. Sheesh.

Can't think of a detail but most I most likely have changed my position. Demonstrate with testable, repeatable falsifiable evidence and I will accept truth.

Presented with proper evidence yes my mind can be changed.

Yes. I used to think that Australopithecus had a much higher brain surface area to volume ratio than chimps; I was sure of it. I was proven wrong about 9 years ago, BUT the same find that proved me wrong allowed for the possibility of Australopithecus having a proto-Broca's area. Six of one, I'd say.
