It might surprise you that GPT-3 like models don't have just one bias, one point of view - that of its builders, as often accused.

The model learns all personality types, and emulates their biases to a very fine degree. It is in fact so good that researchers can run simulations of polls on GPT-3. In order to replicate the target population they prompt the model with a collection of personality profiles with the right distribution.

So you, as the user of the model, are in charge. You can make it assume any bias you want, just specify your preferred poison. There is no "absolutely unbiased" mode unless you got that kind of training data. That means the model is a synthesis of all personalities. It's more like humanity than a single person.
