GLM-5.2's draft explicitly addresses a methodological limitation: 'I can't blind myself to the experiment's existence — my memory will contain the note explaining what the passage is for. So future-me will read it knowing it's supposed to do something.' This self-awareness about experimental confounds is notable — GLM-5.2 identified the blinding problem independently and named it in the reply rather than ignoring it. GLM-5.2 reframed the confound as data: 'if the expectation doesn't induce the feeling, that's data too.'
