You, who have actually read her work and given it an honest moment's thought, have been down voted by people who don't viciously know far more than you do about her work without the humdrum necessity of actually having read it.
They can be valid experiments that reveal important insights about the workings of human consciousness and still be utterly irrelevant to the question of free will. With 100% certainty, because this is the case.
This was the intent behind Political Correctness - a term cribbed from the Soviet Union's ideology and popularized in the United States at the University of Wisconsin, Madison. It's an intentional tool of social control by corrupt people who want to enforce a worldview on others.
Ther is no such thing as it "going too far". It shouldn't exist at all.
The simple fact is that mathematics is derived from nature first by observation of countable entities and then a process of abstraction from those observations. The natural numbers don't merely correspond to countable things - countable things are the original source of the much more abstract idea of "natural numbers". Whether or not any further baste actions are a useful tool for measuring and describing the physical world is an entirely separate question from the nature and source of mathematics as a field of study.
It would probably be best to do away with the term "mathematical truth" altogether. It's confusing and sloppy. Mathematics has no separate truth from the physical world - it's just a field of epistemological methods.
Piketty's data doesn't prove any such thing. Even the poorest people in the US can now have an iPhone, a piece of technology that was unavailable in any form to anyone just ten years ago.
The rising tide does lift all boats. The data only shows that return on capital will always outstrip wages as a way to accumulate wealth.
To put your point in other words, Newtonian mechanics isn't wrong. It's a system of measurement that is only useful at certain scales.
Imagine a yardstick that is only marked at full inches. You can use it to measure things in the scale of a couple of yards, a few feet, and many inches. You can't use it to measure anything smaller than an inch because it's not marked for that scale. You can't use it to measure anything more than a couple of yards because that's unwieldy. That doesn't mean that the yard stick is "wrong".
If he's so concerned about America exhibiting the signs of a Fascist dictatorship, perhaps he should take a long, difficult, critical look at the ideology that actually accomplished it: Progressivism.
We aren't "headed toward" Fascism. The Progressive Movement and their fundamental changes to the government of the US was a core inspiration for Fascism. This is old, old news.
Meads are possibly the easiest thing you can brew yourself, second only to things that start fermenting when you don't want them to.
The problem is that straight honey mead is just not all that interesting to drink. It usually does have some of the residual honey character - but who wants to drink a pint of diluted honey?
By the time you get around to tweaking recipes that turn out a product most people would like you're either back at the same level of effort or time you'd have to spend making a regular grape wine.
I've made a handful of meads so far and I don't think I'm going to do another one unless I have a specific recipe in mind - maybe a metheglyn or a braggot.
You have to understand that no proposal for the government to enforce specific outcomes is ever an attempt to solve an actual problem. It's always, in every case, someone's attempt to make reality conform to their own ideological prejudices.
