For me to disbelieve in the results of the LHC experiments (the Higgs boson not definitively confirmed beyond all and any reasonable doubt, by the way) I would have to believe that scientists and engineers and so forth, internationally numbering almost certainly in the hundreds of thousands altogether at least, every single one of them highly trained for years, have subverted the usual standards of the scientific method - peer review included - and concocted a worldwide conspiracy to conceal the truth or put out misinformation.
If I were that credulous I'd be believing in Jesus.
OK, over the centuries, similar numbers of people have studied the stories about God and Jesus, more recently using scientific means such as literary criticism and linguistic principles and have come to the conclusion that 'yes, they are valid' or 'no, they aren't valid'. Some have started from a 'believing' point of view; others from a 'non-believing' one. Are you suggesting to us that only those who come to the latter conclusion are to be trusted?
Is it really true that hundres of thousands of scientists have been involved in the Higgs-Boson (yeh, I spelt it right this time!!) project? Not quite sure what engineers have to do with the issue since they only build at the instruction of the scientists, they don't (unless they are scientists as well, in which case they would count as scientists for this situation) do the experimentation.
I am also aware that 'the Higgs boson (has) not (been) definitively confirmed beyond all and any reasonable doubt', by the way. However, there do seem to be those for whom the work at the LHC is sufficient for them to believe that it has been. Not very scientific, I know, but then there are scientists and 'scientists'.
