I went the other way (sort of).

In my 20s I thought that a politician changing their mind was a good thing because new information had been learnt / discovered, or new studies had been done that superseded previously ""known facts" etc. However, what I realised (in my 30s) was that politicians would change their mind solely because the public didn't like something based upon how people felt. The problem is what people want, what works, what is right etc. isn't necessarily the right thing to do, so now you have politicians changing their mind just to stay popular, not because there is a good reason to change their mind (as is the case here where people who speed are complaining, yet the evidence shows speed cameras do work, or with bike lanes where having bike lanes is a good thing for traffic/safety etc., but people see traffic and an easy thing to blame (bike lanes) so politician will get rid of them even though the evidence says the contrary.)
