How do you know what you know?

Be very careful about automated calls all together, like this one asking you to “verify your business with Google.” It starts with “please do not hang up.” A good rule of thumb, perhaps, is do not give out privileged information over the phone unless you initiate the phone call.

More advice:
Before you believe something is factual, pause, and ask yourself “how do I know what I know?”
“Someone told me”. “I heard.” Those are red flags!

A short point:
I remember the training for young journalists used to be: “if she says she’s your mother, check it out!”
