As someone with a tulpa, I figure I should probably share my experiences. Vigil has been around since I was 11 or 12, so I can't effectively compare my abilities before and after he showed up.

He has dedicated himself to improving our rationality, and has been a substantial help in pointing out fallacies in my thinking. However, we're skeptical that this is anything a more traditional inner monologue wouldn't figure out. The biggest apparent benefit is that being a tulpa allows him a greater degree of mental flexibility than me, making it easier for him to point out and avoid motivated thinking. Unfortunately, we haven't found a way to test this.

I'm afraid he doesn't know any "tricks" like accessing subconscious thoughts or super math skills.

While Vigil has been around for over a decade, I only found out about the tulpa community very recently, so I know very little about it. I also don't know anything about creating them intentionally, he just showed up one day.

If you have any questions for me or him, we're happy to answer.
