would you follow the herd even though you know they're wrong?

A few months ago advertisers discovered that Facebook had been overstating its video streaming numbers by 60% to 80% for a period of two years.

And according to research company Nielsen, in Australia, the overstatement was much larger than that - an astonishing 94%.

Yet despite the overwhelming evidence about the deception within online advertising advertisers continue to pump money into it hand over fist.

However, maybe using common sense and acting one way when your peers are acting another is a lot harder than people believe?

Check out this ad from US investment company Prudential, which uses some Candid Camera footage from the 60s, as a great example.
