Question

How did pre-industrial tribal societies – for example Inuits, manage to deal with inbreeding even though they were small in size and lacked outside contact?

Even pre-industrial tribal societies had plenty enough contact with other people for inbreeding to not be an issue. The idea of groups of people being wholly isolated is almost entirely untrue. There isn’t evidence that inbreeding has been an issue in past tribal societies.
