How do I hide reviews on Play Store made by my phone contacts?

Consider a random app on Play Store. When I visit its page, the reviews shown to me at the top of the list are mostly by my phone contacts (not Google+ contacts). I do not follow anyone on Google+, although some people might follow me. I have hundreds of phone numbers in my phone's contacts app which syncs with Google. I do not wish to see reviews about an app posted by my phone contacts unless they're actually worth seeing there, I want to see reviews based on their usefulness or upvotes and I want to see reviews from total strangers mostly. **How can I achieve this?** OnePlus One, Cyanogen OS 13.1 non-rooted, stock, up to date so far. Apps including Store, Services, Google+ and everything up to date so far.
