Is the following statement consistent:
``There is no non-trivial c.c.c forcing notion adding a minimal generic real''?
The question is related to Prikry's question: Is it consistent that any non-trivial c.c.c forcing notion adds a Cohen real or a Random real?
See also A special c.c.c forcing notion and adding minimal generic reals where it is shown that the answer to the above question is no, if we assume $CH$ or $MA+\neg CH$ (this follows from the results of Judah-Shelah in Forcing Minimal Degree of Constructibility) Also it is clear that, a model for Prikry's question is also a model for the above mentioned question.
Remark. By a theorem of Shelah, a modified version of Prikry’s conjecture holds in the context of Souslin c.c.c forcing: i.e. every Souslin c.c.c forcing either adds a Cohen real or is a Maharam algebra. Indeed, Shelah showed that any Souslin c.c.c forcing which is not $ω^ω$-bounding adds a Cohen real. See
