Science is based on fact. Scepticism is very much a part of scientific inquiry and what this scientist is expressing is scepticism these results are accurate. Along with the calls by others in the article demanding the results be reproduced in other labs the scientific process is working perfectly here.
The key word here was the quote "believe" which indicated opinion, taste, or faith, rather than unfettered reliance on facts...
On the whole, science tries to pay more attention to facts in the abstract to a greater extent than other approaches to things; but scientists remain human, with their own beliefs, tastes, and cliques, just like other groups of people.
PS did you look up "polywater" ? Cheers!
