Oh!! That is an excellent question.
How can we think better?
For me the Books that have helped me the most are:
It's Not Luck by Eliyahu M. Goldratt

It's a business novel, where Alex Rogo has to decide what to do with 3 factories on his division.
And uses critical thinking steps to come to the solution.
then if you like the approach the next book is:
Thinking for a Change: Putting the TOC Thinking Processes to Use (The CRC Press Series on Constraints Management)
