Personas are problematic when they assume goals and values of users. I've seen many product teams create personas or jobs to be done that literally come from their own idea of what "someone like that" or "someone in this role" would need. Conversely, when we start with the idea that we don't know, define a customer and then ask them unbiased and non-leading questions about what they have done (NOT what they 'want'), it doesn't matter as much whether the framework is personas, JTBD, or any other approach.
