I recently came across a BBC article that backed up my observation about truths.
The following is an extract from the article:

Some people suggest this refusal to think is produced by the system itself - it's the only way our current economic and political arrangements can keep on going. This may be so, but the resolute avoidance of unsettling facts is a deep-seated human trait.
While we live surrounded by unknown unknowns, we live on the basis of unknown knowns - intractable facts that we prefer to forget. We'd do better to confront these awkward realities and muddle through more intelligently. We humans are sturdy and resilient animals, with enormous capacities of creativity and adaptability, but consistently realistic thinking seems to be beyond our powers. This may well be the biggest unknown known of them all - in an age that prides itself on its advancing knowledge and superior understanding, we're as anxious as ever to avoid facing up to our actual condition.
