It’s very easy to tell people that the latest experiment only produced 1% of the power that was put into it. Instead, they were told that the “net energy gain” was positive, and that this was a major breakthrough that brings viable commercial fusion power significantly closer.
I suppose, when you have experiments costing tens of billions of dollars being funded by the public, that this kind of corruption of the truth is inevitable. But that quite understandably undermines public trust in science communication.
