 To avoid confusion, the first of these notions can be specified as “philosophical scepticism”, the second as “scientific scepticism” or “defence of science”, and the third as “science denial(ism)”. Adherents of the first two forms of scepticism can be called “philosophical sceptics”, respectively “science defenders”. Adherents of the third form can be called “science deniers” or “science denialists”. Torcello (2016) proposed the term “pseudoscepticism” for so-called climate scepticism.
