I loved this reflection on the virtues of physical media and what it says about the rot of friction-free surveillance platforms. I still have a tape player in my car and to date no other music medium brings me more joy.

About to go on my first true work-free vacation of 2025 (I hope)! This is one of my final stories for the year, about the extremely humanlike chatbots we've been given and whether they should be that way.

“Privacy nicks come from the proliferation of cameras and biometric sensors on doorbells, glasses, and watches, and the drift of surveillance and data analytics into new areas of our lives like travel, exercise, and social

This is, of course, always where this was headed. Things will only get worse as facial recognition becomes normalized unless lawmakers ban it outright. Next up: precautionary facial surveillance of everyone, all the time, just in case (with guardrails that will also eventually be rolled back).

Behind the gig economy’s promise of flexibility is a game designed to keep workers hooked, argues George Augustus Bachmann. Algorithms, opaque pay rules, and gamified incentives push drivers and freelancers to work more without benefits or stability.

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?

Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"

Text reads: About synthetic panels
Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels.

Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey.

Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away.

Text reads:
Discussion
The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002)
of the variance in behaviour to be explained by intention and PBC.

Well, this is an utter disaster for science.

This gutting of peer review is very likely driven by Project 2025/OMB/Vought, very likely is about funding junk science, and very likely is coming for #NIH and biomedical research next.

in reviewing grant proposals.
The changes permit as few as one outside review rather than the current minimum of three, end the routine use of expert panels to discuss those individual reviews, and give program managers greater authority to recommend which proposals should or should not be funded. They are described in an internal 1 December staff memo that Science has obtained and mentioned briefly in an update to NSF's grantmaking manual posted on 8 December.
A major reason for the smaller staff is the elimination of hundreds of so-called rotators, scientists on loan from academia who served as program managers as well as higher level administrators. Their absence, combined with the new review policy, represent a major change in how NSF
