What a horrible article.
While the _intention_ of the article wasn't to keep people stupid*, that certainly will be part of the effect. "Keep them stupid* so that they don't realise that half of what we say is absolute rubbish."
If the society was a food production company, they would churn out tonnes and tonnes of fast food every year, and their marketing campaign would discourage customers from reading any sort of nutritional advice. Their tagline would read: "No need to think - just eat! Because *we* know what's best for you!!"
