I don't think an idea by itself has much effect. It's not only what is said but who said it.
I suspect during the 50s and 60s in an effort to impress certain advice on people, many quotes were attributed to Albert Einstein. It stands to reason that if other geniuses, like Woody Allen or Yogi Berra, only produced a dozen or fewer really pithy sayings, it's not likely Einstein uttered all that stuff under his name. The name was synonymous with genius in those years. That was promoted and exploited.
As a simple example, somebody came up with the idea to paint the word Ambulance backwards on the front of same so that drivers would see it the right way around in their rear view mirrors. Why you would need the word when a speeding vehicle with flashing lights is behind you I don't know. But I know if I thought of doing that everyone would say what a really stupid idea it was and not paint any ambulances as described.
Perhaps the person had an automotive painting business?
