Critical thinking is a necessary and welcome skill brought forward to any serious discussion. Unfortunately, it’s not always utilized correctly.
In our world of fake news, inaccurate memes and blatant lies people post on the strength that others will not look into the matter, it leaves us more ignorant.
To be critical, there should be some working knowledge of the issue. At the very least, one should look for one more sources beyond self-referential articles (Ryan Holiday tackles this in great detail in his book, Trust Me, I’m Lying).
Our opinions should be formed beyond emotional triggers. Emotions may play a part, but only if they are in-line with a depth of knowledge behind them.
There must also be a willingness to look beyond one’s own worldview, but only if stepping into another that’s at least equally as formed.
Critical thinking does not mean we argue purely based on personal feeling, nor does it mean we accept an opposing view based on nothing.
We need a foundation to work from first. Once that is in place, we can have a serious dialogue.
