It is the instance of using a premise that merely asserts or restates the conclusion i.e. to assume as true what is at issue in the argument.

The argument is circular. The argument is begging the question as to wether the premises are plausible.

What is Begging the Question (broad sense)?

Answer 32

When arguments use premises that are no more plausible that the conclusion is already.

The premises must be individually more plausible that the conclusion is;
i.e.

Premise 1 plausibility > X

Conclusion plausibility = X

If this is not the case then the argument Begs the Question (in the broader sense).
