I can just conclude that the evidence is not good enough, at this time, to settle the matter definitely either way. Scepticism is a matter of doubt rather than denial. In fact this is the characteristic stance of scepticism. A sceptic is someone who calls a knowledge claim into question. Scepticism is dogmatic when assent is withheld on the basis of prior conviction without considering the evidence.
Global scepticism is rare outside philosophy seminars.
Dogmatic scepticism, regrettably, is less unusual. Many of our beliefs, such as those about the content and composition of our immediate surroundings, are relatively immune to sceptical doubts. You don't doubt the existence of chairs and tables, or the paper on which these words are written. Between these extremes lie disputed cases, such as God or economic rationalism - and also psychic and paranormal phenomena. Scepticism of course is not the same as cynicism - though cynicism is a form of scepticism, namely scepticism about the sincerity or goodness of human motives and actions.
