I think it depends. I have Moon in Gemini, square Mercury in Pisces and I RARELY lie.
But I also have an almost exact Moon-Mars and Moon-Jupiter conjunctions, plus Mercury also squares my Jupiter and Mars..so, even though I get tempted to deceive at times, I simply CANNOT do it(friggin Mars, the friggin warrior and that friggin wanker, Jupiter..phew
I am good at being secretive though so I can keep information for years or decades without saying anything, and I have learned that can be deceptive to others.
For instance there are vital experiences from my past I haven't shared with anyone(Pluto in the 3rd house, too) so people can never get me right without those missing pieces of the puzzle.
But I don't withhold vital pieces of info that may affect other people. And I rarely actively lie.
Even when someone asks me stuff like "how do you think this dress looks?" I'll just blurb out my honest opinion before I even realize it. lol
