For those who can't imagine how easy is to produce such an experimental error, the measurements are comparable to what's appeared "unexplained" in the case of the "Pioneer anomaly" until a very careful analysis was made:
It's much easier to produce "some results" then to prove that the researcher didn't fool himself.
Re Pioneer: "once the thermal recoil force is properly accounted for, no anomalous acceleration remains."
Now from the EmDrive paper's conclusion actually confirms that not everything was proved to be "sure" even from the point of view of the authors:
"Although thermal shift was addressed to a degree with this test campaign, future testing efforts should seek to develop testing approaches that are immune to CG shifts from thermal expansion."
Why too much public attention before the whole thing is actually proved can be dangerous:
"When the results of the Cannae Drive prove impossible to validate (as will almost surely happen), it may produce an unjustified cynicism about how NASA has failed us once again."
It's just a very small team "devoted to exploring unorthodox propulsion ideas." "The reality is that space exploration is expensive, difficult, and time-consuming. Therein lies both its challenge and its glory."
