Lazyness - I guess one can call it that (the reason why we don't bother to investigate what should be followed up). But I think there is more to it.

Most of us have an innocent faith in the intentions and doings of our fellow beings, especially in those of authorities and recognized icons. (It is this blind trust that makes us easy targets of those well versed in the art of deceit.)

This trust in the trustworthiness of our fellow beings is deep seated - as old as the roots of social existence. And I think it is a resistance in us to upset this most basic component of social capital that inhibits us from discovering flaws that may threaten our very existence that makes us tardy to investigate.

What do you think?
