Often. If you want expert results, you want to exploit the portion of the weights with expert viewpoints.

That isn't always what you're after. You can, e.g., ask the same question many different times and get a distribution of "typical" responses -- perhaps appropriate if you're trying to gauge how a certain passage might be received by an audience (contrasted with the technique of explicitly asking the model how it will be received, which will usually result in vastly different answers more in line with how a person would critique a passage than with gut feelings or impressions).
