I score above the 95th percentile every time I do it, it is antithetical to actual critical thinking to have a set of ridiculous rules that don't apply to real multifaceted issues. It is testing your ability to follow a process. I would also add to this that my final year project in a highly theoretical science subject was just recently published, not to brag but because I find the idea that taking a philosophy class and reading books will unlock some form of critical thinking truly present in a ridiculously (and scientifically) flawed test.
I congratulate you for that. I'm sure you are very smart (I'm saying that unironically - I appreciate it sounds sarcastic).
At the same time, there are transferable skills. Of course, in real life for application understanding and following strong meaning is more important than following weak/literal meaning. But identifying specific arguments alone is a skill that the majority of the population lack, even before identifying argument strength. Im sure from a science background, you might be good at it. But the majority of people are not currently good, and it's part of the reason that people get away with bad arguments all the time in the real world. Of course, the WG tests generally don't present arguments in the best way, but it is still testing for something. "Pancakes and waffles" or so the twitter saying goes.
Reading a block of text and identifying what it is saying in the text is also a skill. Again, in real life identifying strong meaning is just as important as identifying literal meaning - but the majority of people, when presented with a news article or scientific article often misinterprete it, or extrapolate false information that isn't in it. That's what that skill is testing.
Deductive reasoning is again a skill that many people lack. Again, in practice it's not the same as WG - it's much more complicated. But the theory is, if you can't learn it to the extent of doing it on a WG, probably it's not something you'd be good at on a large scale. I see the value in the way it's tested...
But feel free to agree to disagree on this. I will always die on the hill that they are much more objective than SJTs.
Edit: I admit it's flawed. But it's a much more objective test than SJT. For me though, the more objective test I've taken so far I think is the
Osborne Clarke verbal and deductive reasoning tests, even if it was more about handling time pressure than anything.
