I personally narrow the definition of a "weasel phrase" to anything which sets up an embedded command.
An embedded command is simply a command embedded into (usually innocuous) speech. As such, it is spoken like a command, rather than a question.
"go into trance", "feel yourself relaxing" are both commands.
"going into trance", "feeling relaxed" are not. These are far less effective.
So a weasel phrase is anything like: "What's it like to X?" (command tone down) "...people simply X" "I wonder if you can X" "...before you X..."
Embedded commands are like breathing properly: to do it once is insignificant as compared to when you automatically do it every time you speak. People are also less likely to act upon them in text.
Embedded commands are just one form of analogue marking.
I remember the first time I was practising embedded commands in a group. One woman was a little bit concerned about looking like an idiot, and decided to chat instead of practice. She started blabbering on about "whenever I try to do something like this I just MESS IT UP". And then one of the guys who'd been doing OK got drawn into the conversation with "yeah, I know what you mean, it took me a long time to LEARN THIS FULLY". She retorted with "I've tried doing it but FIND IT REALLY DRAINING".
I was pretty amazed and started to listen out for the difference in analogue marking between congruent and incongruent communication. It was only then that I started to realise that people do this naturally.
Embedded commands use a command tonality. Analogue marking is done with any distinct tone or gesture and often happens over the course of 2 or 3 sentences. Also, analogue marking doesn't have to make sense.
I could write randomly in a paragraph LIKE this, almost any COHERENT sentences, and only then REALISE what I've MARKED out.
So I've marked them as I heard them in my head, and had you heard me verbally, you would have now have those words associated.
AFAIK, this form doesn't go through your auditory cortex and the rest of your brain doesn't care about sentence structure or verb tenses so...
Make a 2 minute recording of yourself talking about something you're congruent about then something you're incongruent about. Go through it and notice all the analogue marking. See if you do it the same as everyone else on the planet.
