The more technology we have, the higher the minimum standard of intelligence, and the greater the need for each citizen to have a perfectly functioning bullshît meter. This is the highest priority of education.
Should be, but sadly isn't; the incentive is to feed into the economically incentivised "bs" rather than be wary of it, which is just... disheartening. Schools often inculcate this enough on a subconscious level that I've seen my fellow college mates rather unable to shake off that residual behaviour.
