I do think that's a fair point (I certainly don't want to encourage people to think hard but non-usefully).
The way I attempted to approach that problem was to have the lower/easier things on the scale be optimized for being easy to get started on (I think the difference between "think seriously for 5 minutes" and "have an actual model of why you think this makes sense" and "not have those things" is fairly extreme, and people who aren't even doing that should do that).
But I also intended to have it quickly escalate to "think about how to empirically test it, and/or actually empirically test it if possible." (Not sure if this addresses your concern but I edited the post to make that a bit more clear)
Epistemic Effort: Thought seriously for 5 minutes about it. Thought a bit about how to test it empirically. Spelled out my model a little bit. I'm >80% confident this is worth trying and seeing what happens. Spent 45 min writing post.
I've been pleased to see "Epistemic Status" hit a critical mass of adoption - I think it's a good habit for us to have. In addition to letting you know how seriously to take an individual post, it sends a signal about what sort of discussion you want to have, and helps remind other people to think about their own thinking.
I have a suggestion for an evolution of it - "Epistemic Effort" instead of status. Instead of "how confident you are", it's more of a measure of "what steps did you actually take to make sure this was accurate?" with some examples including:
[Edit: the intention with these examples is for it to start with things that are fairly easy to do to get people in the habit of thinking about how to think better, but to have it quickly escalate to "empirical tests, hard to fake evidence and exposure to falsifiability"]
A few reasons I think this (most of these reasons are "things that seem likely to me" but which I haven't made any formal effort to test - they come from some background in game design and reading some books on habit formation, most of which weren't very well cited)
Results of thinking about it for 5 minutes.
Next actions, if you found this post persuasive:
Next time you're writing any kind of post intended to communicate an idea (whether on Less Wrong, Tumblr or Facebook), try adding "Epistemic Effort: " to the beginning of it. If it was intended to be a quick, lightweight post, just write it in its quick, lightweight form.
After the quick, lightweight post is complete, think about whether it'd be worth doing something as simple as "set a 5 minute timer and think about how to refine/refute the idea". If not, just write "thought about it musingly" after Epistemic Status. If so, start thinking about it more seriously and see where it leads.
While thinking about it for 5 minutes, some questions worth asking yourself:
