You get more Likes.
People leave “agree” and “so true” comments, which feels good for the ego.
It blends you into conformism, adding to your brand image.
You upset fewer people.
You don’t have to cover lengths to explain your ideas and points; others already understand.
You get more followers, fans.
You get literal highs due to dopamine from ping notifications of “Mathew Branchester reacted to your post”.
Of course, giving in to populism — which, in the current political and social context, is more extreme and almost abusive — also comes at the cost of values, compassion, and personal growth.
But hey, the incentives are too good to care about the meager cost.
