The question asked in the thread title is rhetorical because the obvious answer is "Yes, people are less trusting".
In addition to what I said in post #13 think about this:
Used to be when you called someone either they answered or you got a busy signal. If they didn't answer they weren't home or didn't want to talk on the phone to anyone - there was no "screening", no caller ID, no voice mail, no answering machine. That has changed drastically. Whether they're home or not, many people don't even answer their phone unless they know the person calling......and even if they do know, they often don't want to talk.
Used to be hard to find out information about people. Now with the click of a few computer keys or your smartphone you can find out someone's address, where they work now and their work history, how much they paid for their house, whether they have a criminal record, and a lot more.
I've seen stories about people who got into a dispute with someone online and later the person showed up unannounced at their front door or at their job, or the parking lot of where they shop for groceries.

mg1: Or, just as scary, someone develops a crush and suddenly "Hi! I'm XX from (website)." Yikes. :wtf:
Online dating has made it easier to find romance, but also easier to become victim of a scam or predator, or whackjob.
Back in the day terms such as sexting and cybersex were unheard of.
Used to be that in order to catch a shoplifter the manager had to watch a person and follow them around the store. Not anymore - surveillance is everywhere, inside stores and even in the parking lot.
Because of lots of incidents, people don't always trust law enforcement.
