YOUR parents were right about getting a good education. It’s not so much so you can understand E=mc² or chart a career path in neurosurgery. You need to keep your brain cells fit so you can tell the difference between real knowledge and what parades as fact these days.

Like you may think something tagged “history” or “science” can be trusted as scholarly or at least reasonably well researched. The TV version of history and science though is dodgy. It’s served up as choreographed reality shows about truck drivers and pseudo science applied to prop up theories that aliens arrived on earth to mine gold, build Mayan temples and to turn grassy fields into circles of artistic whimsy.

Ever notice “experts” quoted have PhDs tagged on their names but are never linked to an institution or organisation? And why is it that at the end of every programme the finding is “inconclusive” or “the jury’s still out”.

You can’t even trust bubblegum wrappers to impart “Did You Know” wisdom clearly. On a wrapper: “Hang gliding is a sport in which a pilot flies a light and un-motorised aircraft called a hang glider”.

You have to separate real meanings from fancied-up drivel like “pre-loved” is “used”; “we have contingency plans” means “we haven’t got round to that yet” and a “cellphone upgrade”, is a freebie you’ll be paying more for. Think about it!
