The really hard part of critical thinking is training your intuitive, heuristic filters. Applying rigorous critical thinking to everything takes way too long. Conversely, applying critical thinking to nothing at all makes you a gullible idiot. Developing that filter to strike the right balance is a lifelong learning process.
Sure, but if I could turn the societal dial a few clicks toward critical thinking vs day dreaming, I'd do it.
The unquestionable success of the Scientific Method has shown that careful analysis and requirement of experimental proof far outstrip bumbling about with our own natural human level of random thoughts that we label "creativity".
But then I look around and see more need for creativity now than ever. Technology is changing faster than ever and that's impacting society in ways previously only speculated about. To me that means there's a lot of opportunity out there waiting to be captured by people crazy enough to do a little dreaming.
Open your mind too far and you accept too many wacky ideas. Close it to much and you'll never see what's possible.
