Not too surprising. Nothing necessarily says 'disbelieves in God/gods' means 'is a rationalist/sceptic'.
And nowadays, it seems like a growing number of people are simply not believing in the narratives provided by organised religions and churches, while still maintaining beliefs about other supernatural concepts like reincarnation, ghosts, an afterlife, etc.
In some sense, it feels like a bit of a pagan resurgence in some parts, with more people being open to the supernatural while still not believing in religion in the traditional sense.
