𝗔: "I just took a personality test at work. It turns out I’m an 𝗜𝗡𝗧𝗝. It explains everything! My leadership style, my need for 'deep work' time—it’s like they looked into my soul."

𝗕: "An 𝗜𝗡𝗧𝗝, huh? Tell me, if you took that same test again in a month, what do you think you’d get?"

If a scale told you that you weighed 150 lbs today and 180 lbs next Tuesday, you’d throw the scale away, wouldn't you?"

𝗔: "Wait... so it’s not even consistent?"

𝗕: "Not even close. Furthermore, the test forces you into 'either/or' boxes. You’re either an Introvert or an Extrovert. But human traits follow a 𝗕𝗲𝗹𝗹 𝗖𝘂𝗿𝘃𝗲. Most people are right in the middle.

It’s essentially 𝗔𝘀𝘁𝗿𝗼𝗹𝗼𝗴𝘆 𝗳𝗼𝗿 𝗣𝗲𝗼𝗽𝗹𝗲 𝗶𝗻 𝗕𝗹𝗮𝘇𝗲𝗿𝘀. It gives you a nice label to wear to lunch, but it predicts almost nothing about your actual job performance."
