There is a good book on the subject, titled ”The Design of Everyday Things” by Donald A. Norman. People develop expectations about how things are supposed to operate based on the appearance of those things. Push/pull doors often violate those expectations, so really don't work very well at all.
In the US, we have been trained by fire codes to expect doors to open outward. Doors perform the worst when their installation violates good design and violates fire code rules.
