Ever-since Descartes –  dubito ergo cogito, cogito ergo sum, the western culture had considered that a person becomes truly human only after they actively start looking for answers. Start thinking about their own persona, in a conscious manner.
Otherwise put, we start existing only after we notice our existence.

The corollary of this concept had been ‘rational thinking’. The belief that it is possible to consider something – to emit a judgement about a subject, only after dispassionately examining all available facts – and only the facts, pertinent to the matter.

While the ‘thinkers’ were coining the concept of rationality, the more practical minded had come up with the scientific approach. Gather as much information as possible about the subject you’re interested in, interpret it and come up with a conclusion. But keep an open mind about any new information which might come up and be prepared for your conclusion to be invalidated – or, at least, ‘nuanced’, at any moment.

At first sight, there isn’t much difference between these two approaches. Only at first sight, of course…
Those who consider themselves to be ‘rational’ have a hard time accepting other people’s conclusions while the bona fide ‘scientists’ are actually happy when they are contradicted. ‘My work has been considered important enough for somebody to check it. I’ll just have to make amends and all will  be fine’.

Now, I’m convinced that you’ve all figured out that I’m joking.
There’s no such thing as a fully rational person who denies the facts which happen to contradict their conclusions just as there’s no such thing as a scientist pure enough to actually enjoy being proven wrong.

But I’m not joking when I observe that there are so many people who consider themselves to be rational and who refuse to accept as fact anything which contradicts their beliefs. Who have a ‘scientific’ approach. Who cherry-pick only the facts which confirm their theory and dismiss – as ‘fake-news’, all the rest. Just as many as the scientists who do the same thing.

I wonder who supervises their thinking processes.
Are they truly aware about what’s going on inside their heads?
Or about the consequences?
