Just want to improve my critical thinking
I'm naive actually and want to stop being deceived and to read between the lines.
I also want academic excellence of course...
I don't know that this belongs in Physics & Math but you can read articles about what critical thinking might entail and then do more of that. That can mean starting from "first principles" or just starting from a blank slate, it can mean ignore the media or culture or politics and just figure out for yourself whether the supposed facts are actually "factual".
Is something "fair"? What does that even mean? Does it even have meaning in every context. If you slip and fall off a cliff is that "fair" or does it actually have no meaning in that context?
You can put things into perspective, use rank, zoom out for a wider perspective, ask "what could go wrong", think in terms of 2nd and 3rd order consequences.
For example "The rich get richer and the poor get poorer". Think critically, are the poor actually getting poorer? Is the US debt just a matter of raising taxes a little or is it too large for that? What are the 2nd and 3rd order consequences if you make a large change to the system? If you double the taxes, what actually happens? Do you just raise more taxes or do you reduce productivity, incentives, cause productive people to move, lose jobs, etc.
Are the rich actually not paying their fair share? What is a fair share? How much are they paying? Do you actually know or are you just repeating what you've heard in the media.
If the narrative is that interest rates, mortgages, car loans are high, is that true? What is the historical average for interest rates? Are rate now actually just average?
Are housing prices too high and unaffordable? Look at other developed nations. Are house prices cheaper there? If not, they aren't unusually high here.
Are wages too low? Are they higher in other developed countries?
Critical thinking means that it's not about the answer. The answer is whatever it is. It's the process that matters.
