You're basing this because you understand technology. If you put yourself in someone else's shoes and ask "Why wouldn't this email be genuine?" then you'll see.
It's all about educating people who use computers. Quite frankly the majority of people couldn't give a damn in the file type, size, code etc because that's all jargon; they see an email from say a bank (say their bank) so why would they question it?
I think people are not thick, just many people don't really *get* technology. For instant if someone explained some complex science jargon about rockets (unless you know science
) you'd go "Don't understand. Can we press the big red button still?".
It's all about information out there and learning about technology. And the truth is there's probably a lot more people who just use the Internet willingly that ones that do not.
Obviously there's common sense involved but to one's eyes a simple say PayPal email saying "click here to reset your password" may not set off alarm bells. You can't be paranoid if you don't understand what to be paranoid about
Especially the elderly and older generations. So I wouldn't like to call someone thick for it, I'd like to treat it as "uneducated" or "aware of the dangers".
