I think this is a part of the average human, and always has been. Possibly (but not necessarily) always will be.
For the most part, the majority of people will act like this.
The bright side is that the world does not require the majority of people to agree in order to change or move forward.
It only requires it's leaders to understand those things.
Sometimes those leaders are the non-majority, non-average humans who do understand facts, do learn from them, and do make decisions that will impact humanity for the better.
These are the times where progress happens in leaps-and-bounds.
Then, the majority, average humans are all taken along for the ride and, basically, forced to accept the new paradigm via rules/laws/charters-of-rights/...
When the leaders are average humans, we get very little progress. Sometimes for very extended periods of time. But, because the average human doesn't like facts but likes to "stay where they are"... we don't regress (much), either.
Here's hoping for non-average leaders!
...or something like that?
