i like title-less because it describes range without pretending you got that range for free. you outgrow a single role after you spend enough time doing different kinds of work.
you start with curiosity. you read across fields and build context. i call someone a generalist after they can use that context to make decisions and do the work.
some people use the label to cover a skill issue. they move to a new subject when they reach the part that demands patience. they discover gaps when they try to execute and choose another subject.
you build range by going deep several times. stay with one skill long enough to make mistakes and build judgment. repeat the process in another field and bring that judgment into a new problem.
after enough repetitions, you may outgrow one role. you can see a problem from more than one angle and take responsibility for the part that needs work. i use title-less for this person.
people on early-stage teams handle tasks outside their job descriptions. researchers and small creative teams face the same overlap. a title-less person can follow the problem without waiting for someone else to own it.
i hold polymath to a higher bar. you need to produce deep work across fields with little overlap. people who know the work should have enough evidence to use the label without your help.
