A scientist engages in evidence-based decision making, whereas an ideologue engages in decision-based evidence making. Which one are you?
Do you read a range of opinions and consult evidence from different sources before you make up your mind? Or do you cherry-pick stats and studies that suit your predisposed attitudes, and overlook anything that’s inconvenient to your opinion? Do you let your political identity (liberal, conservative, socialist, libertarian, whatever) dictate how you should feel about something, based on whether it’s a “left-wing” or “right-wing” issue? Or do you look at each issue of public policy independently, and realize that the world isn’t easily divided along a black-or-white dichotomy?
Once you’ve allowed yourself to be told how to feel about something because of what your political identity is, that’s when you stop being an independent thinker, and start being a partisan hack. Life isn’t about good or bad, left or right – it’s about choosing the best (or in some cases, least-bad) option amongst many. Never forget it.
