Unpopular opinion
I think it’s more important to understand how you get to an opinion than what your opinion is. If you start off with a bad premise and a bad way of working with information, then no amount of good data or reasoning will help you. Conversely, if you have a solid premise, a good understanding of the limits and biases in whatever analytical tools you use to process information, then you have the tools to end up with an ideal, or close to ideal result, no matter what batch of information you have to work with. This means that you’ll end up with a good stance no matter what subject or field you’re trying to learn about or get established in. School at it’s best isn’t about an information dump, it’s about learning how to learn effectively.
