I wish I had an objective test. All I can go by is the difficulty I experience solving problems and my progress at work. There are certain classes of problems, boolean logic for instance, which used to be second nature to me but now leave me feeling blank and without even a hint of what the answer is. It even shows up in everyday life. I encounter more and more situations where I can't take the available information and generate a solid decision... I end up 'YOLO'ing it a lot and just taking a guess. I'm trying to come up with coping strategies, like writing things down and using visual tricks, but it doesn't work most of the time. It's frustrating and scary. I don't even know if I could transition from a tech role into management because I am so unfocused and unable to think.
