It goes in both directions. The further you are from the dominant ideology you grew up in the more work you had to put in to get away from it - and while in general following research and evidence-based claims will push you to the left, that doesn’t mean that there aren’t an awful lot of people who get pushed to the left by non evidence-backed things, like their own anecdotal life experiences or just an internet personality that they jive with, so I wouldn’t say that going left is always harder than going right.
