My neighbor was trying to open an Amazon store front, but of course Googled the phone number to call instead of actually visiting Amazon's website. She called the number and spent over 3 hours on the phone with them linking her bank accounts to her new 'Amazon store front', they even had her install VPN apps onto her phone to gain access of it. Her husband asked wtf was taking so long and grabbed the phone from her, he instantly new it was a scam. She called her bank from another phone and they had already gotten $16k out of her accounts while she was talking to them. The crazy part is, the bank saw some pending transactions for thousands more, and wouldn't cancel or put a stop on them, they claimed they needed them to process so they could track down the scammers... 2 weeks later she is still trying to get her money back from the bank.
I'd consider her a normal to above normal intelligent person, but still got outsmarted by a scammer, probably because she didn't know what the process was, so she believed whatever they told her.
