I could see that in a proportional-representation system. If 10% of the population is really into homeopathy, they could vote for a party that represents those interests. But the UK has a first-past-the-post system, like the US, meaning members are elected by getting the most votes in a specific district. Is Tredinnick's district really majority in favor of astrology being funded by the NHS? My guess is no, and that he's elected despite this issue, not because of it. Incumbents are very hard to knock off, especially outside of marginal districts (his district is a Conservative stronghold, and the UK has no party primaries), so he keeps winning regardless of whether his district's residents think astrology is useful or not.

The American tradition of liberty is not one of unrestricted direct democracy, aka mob rule, but of an ordered republic with checks and balances and structural limits on what can be accomplished via elections. At the Founding, judges were not elected; that is a recent (20th-century) innovation in some state and local court systems, not traditionally part of the American approach to the justice system. Juries were selected from amongst one's peers, and judges were appointed for life tenures, from among those learned in the law.

More likely, there will be a basic set of functionality that can be used by Mr Below Average coder to generate a bunch of spurious correlations.

I don't think getting the machine learning to "work" is going to be the hard part, in the literal sense of the code running and generating stuff. But if you have no understanding of statistics, the conclusions you draw are likely to be invalid.

A lot of math grading has a subjective element. At least when I was in school, you usually had to show your work on math problems, and could get partial credit. For example if you correctly analyzed a word problem, set up the equations correctly, and then made an adding error at the end, you'd get some points despite the wrong final answer. Continues at higher levels, e.g. when doing proofs.

It's possible to reduce some sources of bias by using grading rubrics, specifying precisely what you'll get points for (X points for setting up the equations, etc...). Some people dislike rubrics because they're very mechanical, but in some cases that can be an advantage, since it removes the judgment around "ah well they got it 90% right"... without points assigned in advance, the assessment that someone got it "90%" vs. "70%" right can be influenced in large part by the teacher's prior belief about whether the student understands the material.

That was my first thought. On the one hand, I can believe some departments offering this really do have good intentions. But will they be able to resist the urge to do more with that surveillance video once they have accumulated a bunch of it? Seems ripe for data-mining and building various kinds of circumstantial cases against frequent buyers/sellers.

In the UK case these ISPs mostly also run other media services: Virgin Media is a big media conglomerate that owns a bunch of TV channels, and Vodafone and EE both sell streaming-television services. A blocking/QoS war could be damaging to all of them, if they start preferring their own services and degrading other companies' services, so it might make business sense to just mutually agree not to do that.
