If you have a Netflix subscription, you really need to go watch The Social Dilemma, a documentary on the ways in which social media manipulates us.
The “dilemma” is multi-faceted. Advertisers vie for our attention across our myriad social media platforms while programmers continuously revise their algorithms to make their product ever more addictive. Higher social media use correlates with self-reported declines in mental and physical health and overall life satisfaction. And yet, we continue to scroll our lives away.
The documentary is comprised of interviews from a host of former social media executives and programmers, spilling insider information about the more nefarious aspects of social media design. I found it to be informative and enlightening, and, yes, a little frightening. I’d recommend it for everyone, but especially teens and their parents.

Only the truly ignorant (Shallow Thinkers) lazy and dishonest allow themselves to be manipulated by the Social Media giants. Fortunately I grew up during a time when Research and Critical Thinking was necessary unless one wanted to rely on My Parents Told Me or My Preacher Told Me.
If you watch the documentary, I think you’ll see that social media is used to manipulate more than the individuals you refer to as “ignorant” and “lazy” and “dishonest.” Many young people, for example, are susceptible to this but it wouldn’t be fair to label them this way.
