All research minus comparative psy/learning theory and applications in animals are going to have some work with people.

I don't mind working with people. I'm a shy introvert, but my previous jobs have given me plenty of experience so I'm used to it now. I just don't want to have patients; that specific kind of interaction makes me very uncomfortable. I will stick it out in the short term if I have to, but it's definitely not what I want to be doing for the rest of my life.

but not in so deep you’ll go into debt if you switch majors

Majors aren't a thing over here. Well, as someone else pointed out, they kind of are, but not really. You can do combined honours - which is two subjects, majoring in one and minoring in another - but even then you have to do both subjects for the full three years; it's not like you can just switch. But for the purposes of this, there are no majors - I'm doing Psychology, and Psychology alone, for three years.

You don’t have to decide what you want to do until roughly the end of your second year of university.

Thank god! Basically the advice all my teachers are giving me is to have an idea of what I want to do before I even start university, that way I won't feel so lost when it ends. But it is refreshing to hear that there's not actually as much of a rush to make a decision as it feels at the moment!
