...Now begins the fun. Warwick Hughes, an Australian scientist, wondered where that “+/–” came from, so he politely wrote Phil Jones in early 2005, asking for the original data. Jones’s response to a fellow scientist attempting to replicate his work was, “We have 25 years or so invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it?”
Isn't that what science is about? Trying to find something wrong with it?
