What's the history around this? And don't these protections only relate to criminal proceedings?

edit: seems the parent is referring to the historical entity of the mere evidence rule which isn't the same as saying that the Framers believed a certain interpretation for the 4/5th amendments.

The right against self-incrimination is limited in civil trials. Additionally, unlike criminal trials where a jury will be instructed that a defendant's refusal to answer cannot be construed as evidence, there is no such instruction in civil trials, and it is common to argue that a refusal to answer indicates hiding something.
