- Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives.

- See if you can find reasons for rejecting it. If you don’t, others will.

This is good advice IME. Get well acquainted (like REALLY well acquainted) with opposing viewpoints, such that you could argue them better than their proponents. See also "Argue Well by Losing" by Phil Haack [1].

Somewhat relatedly, the ancients viewed Rhetoric as the purest expression of intelligence. It required you to have deep knowledge of a topic, including all arguments in favour and against (implying deep empathy with the audience), and the ability to form coherent and meaningful argument. Modern political "debate" is ludicrous in comparison.

I always felt like Congressional debates should begin with each side trying to explain the opposing position, with debate only beginning when each side agrees with the opposition's framing of their PoV. I also recognize how naive and idealistic this sounds.

The public Congressional debates are performative, intended to curry favor with key voters, campaign donors, and media personalities. The substantive debates happen in private using completely different rhetoric. This is mostly fine in that it allows for policy decisions to move forward with compromises. The problem is that some members of Congress are unable to shut off their deranged public personas even in private back room negotiations.

I've also found simply testing a hypothesis without reasoning about it can quite often outdo your own reasoning and the reasoning of everyone else. Sometimes you are wrong, and everyone else is wrong, and only an empirical test can separate the wheat from the chaff.

Although maybe this method only works for me because I am a moron, and many people can out reason me, so the only way I can discover anything is to do something all reasonable and rational people are already sure is wrong.

Happens all the time.

Not for the vast majority of political issues and indeed for most of Social Sciences. In these cases, empirical evidence is just an accessory, it's still evidence but it's never conclusive, you need reasoning to sort out the complexity.

"Rhetoric" is an unfortunately overloaded term, as modern political "debate" is often nothing more than (the other definition of) rhetoric.

It is very similar to Feynman's

  The first principle is that you must not fool yourself--and you are the easiest person to fool. So you have to be very careful about that.
