It depends a lot where you study it, really. All psychology degrees will include at least some scientific content due to BPS accreditation requirements. Some departments are very heavy on the science side of things though (e.g. UCL, Oxbridge, KCL) while others focus more on other aspects e.g. clinical or the social side of things etc. If you're in one of the latter courses that just includes the amount needed for the BPS accreditation then it's probably not unbearable as above - but you might want to avoid courses that fall into the former category!
