Conservatism and liberalism versus easing and aggravation

Do you think there is a direct connection between the ideological axis of “conservatism-liberalism” and the halakhic axis of “severity-relaxation”?
 
In other words, the more conservative a rabbi is (for example, Haredi, Haredi, or even more distinctly Haredi), the more strict he tends to be in ruling, and the more liberal a rabbi is, the more lenient he tends to be?
Or there is no necessary connection between worldview and the actual level of aggravation.
