My gut instinct is to agree with you... but I think we should be a little more sympathetic, since we have so many examples of seeming smart people falling for various scams.
I think it is foolish and wishful thinking to think we are immune to being scammed just because we can see through all these ruses when we read about them online.
Whenever something bad happens to other people, our immediate first reaction is to find out reasons why it would never happen to us. We wouldn't fall for it, I wouldn't put myself in that situation, I would see it a million miles away, I would have done this instead..... this is a defense mechanism because we don't want to feel vulnerable... we want to think that bad things are preventable, and we would always prevent the bad things.
This is simply not realistic, and gets in the way of empathy for people in bad situations. Just think back in your own life when things went wrong, and how looking back there are always things you could have done differently... but you didn't, because you are human and make mistakes and didn't have perfect knowledge of what was going on like you do in hindsight.
