@Njord I honestly don't know, because I'm not sure what constitutes "conservatism".

The things I've mostly changed my mind about as I've grown older have been technology (I'm a lot less enthusiastic, and arguably "conservative" in that I've found myself resisting more technologization than younger me would have guessed!), and the EU (I used to be a die-hard left-Euroskeptic, now my views on the EU have moderated quite a bit - which younger me might also have considered "conservative").
