You can't beat their model because they don't include all the data they use in the competition dataset. It's a highly sanitized and simplified toy problem used for hiring and marketing. They don't even tell you what the features are so it's impossible to use domain expertise to constrain the fitting problem (this is a critical component to building profitable trading models because of the signal to noise ratio in the data)

Regarding bias training that you mentioned, the Heterodox Academy did a literature review and concluded that there isn't adequate evidence to conclude efficacy and if anything the effects are deleterious on workplace cohesion.

It was largely a fashion trend among executives as well as a fear of being singled out as being not onboard with BLM. It's better to be with the crowd, at least you are immune to specific criticism.

We saw a similar fashion trend in company cancellations of Facebook ads, multiple companies cancelled their ads for a short duration at the same time (each cancellation catalyzing the next) and we've heard nothing about that since.

I find it quite interesting honestly.

Having an apolitical workplace is not the same as that workplace saying that all things are fine. It just means that you keep discussion of political topics that are orthogonal to the mission of the company out of the workplace. A company is optimized around its mission and the usual hot button political issues can only serve to be a distraction that saps productivity and effectiveness.

Standing for dismantling racism is always correct, but that's distinct from explicitly stating support for the Black Lives Matter political organization.

If you don't agree with some of their stated objectives, tactics, leadership, it should be OK to refuse to offer support, and that doesn't automatically imply a tacit support of racism, and it doesn't automatically imply resistance to lower-case black lives matter.

This would be a great exercise for primary school kids. Touch typing is an important skill and once it's learned it's with you forever. On a platform like this they can also practice reading and comprehension, and the teacher has a way to ensure that the reading material was indeed read. Ideally it'd be coupled with some comprehension questions to make sure the kid didn't go on autopilot.

I'm not an expert in pedagogy though so take that with a grain of salt.
