That's an unscientific conclusion. They say the effect (of high variation) is unattributable, so it's unfair to limit it to soft sciences. This could infect literally any human endeavor that generates measurements, hard sciences included. Or, as another poster observes, this result itself is affected by high variation and we end up in a Godel-ian loop of "this study is false" results.
