YUP. It's bc we have active brains and engage in metacognition. Also usually means a high IQ, and strong compartmentalization skills. It's possible to practically have multiple personality disorder without having only one 'persona' front at a time. With a high enough propensity for thought, plus constistent active novel trains of thought (your own thinking, not from social media or echoed rhetoric), and a lack of severe enough trauma to cause the DID system.
