Paul's ongoing revelations about nothing in particular, what he likes, what he thinks etc. suggest a very symbiotic relationship with the media: they need to keeps the Boomers happy and he needs relevance assurance. He was in a great band. In that band he wrote some truly appalling songs and pushed them down the road toward the mawkish & the music hall. John wrote some drivel too. Paul's solo career was based on the road he'd started along in the Beatles. John started of strongly but he ended it writing the mawkish domestic stuff Paul would've been jealous of.
Did Paul write intuitively? I would assume, like most songwriters, he did often enough, early enough but there's plenty of evidence to the contrary as well. In the end he seems to be, subsonically, singing the chorus of "Love Me Do" in every interview.
