I've had a lot of success with getting ChatGPT [1] to do thorough research with the following prompt combined with Deep Research:
X=[claim]
Do a deep dive into X. Tell me the steelman arguments in favor of X.
Then tell me the steelman counter-arguments to X.
Then tell me the steelman counter-counter-arguments to X.
Then tell me the steelman counter-counter-counter-arguments to X
Think like a rationalist in the LessWrong style. Think with probabillties, using Bayesian reasoning, looking for discomfirming evidence, think critically and skeptically, problem-solve around potential obstacles.
Basically I get ChatGPT to play steelman solitaire.
Here are some examples I've done to give you a flavor:
- Is fiction a superstimulus that you should minimize?
- Is Israel committing genocide in Gaza?
- Should you aim to mimic the diet of hunter gatherers?
- ^Starting with 4o, then o3, and now 5-pro as of this writing 

Your second bullet point appears to have been blocked/does not load for me at least
Thanks! You mean the Israel/Gaza one?
How about now? I tried changing something.
Thanks, yes that works now
