On Twitter @dhinckley said that according to Moz over here, 302 redirects pass zero "link juice," also known as PageRank. John Mueller said that is not true.
Here is a screen shot from Moz:
Google's John Mueller said in response, "I don't know about "link juice" but I do know how PageRank is handled." "There's still confusion on 302/301 from the olden days; 302s are fine," he added.
In fact, last month, John Mueller said 302 redirects pass PageRank.
@dhinckley @randfish I don't know about "link juice" but I do know how PageRank is handled.

So, do not believe everything you read out there, including what he read here ;-).
