Withholding evidence isn't a defense against criticism. If you won't TELL ME your effect size, but you do tell me the sample size, I can certainly say, "I am skeptical of your conclusion, because of your sample size."
Criticizing the stats of an article that hasn't been published b/c of science news reporting on it is an exercise in madness.
Criticize the science news instead.
You should instead say "I am skeptical of your conclusion, because I don't know your effect size."
