Just because there are more studies doesn't increase their quality. The right way to do a systemic review is to assess studies based on their quality, such as design against bias, their size and method to include a combination of good studies and exclude the poor ones. Then assess those studies. Most studies are very low quality and combining them doesn't increase their value or their chance of being right, high quality studies are much more likely to be of value and ground truth and the better the methods and size the greater the chance of something that we can trust.There is an awful lot of junk in Psychology in general, it has a serious replication issue and bias due to poor methodology resulting in a high chance of fake and biased results. So no you can't assume the accumulation of many studies is better than one, that is not how systemic reviews work.
