I'm not sure where I should post this question, I will try here. It's a linguistic doubt. I am not a native English speaker and I don't know the difference between 'data cooking' and 'data rigging'. Which one sounds more offensive or can be considered a more serious fault for a scientist? How would you call in English some method of data processing and analysis not totally objective and influenced by the result we would like to obtain?. I think the author don't want to lie but is using an incorrect trick to get misleading good results. I'd like to be clear but not very rude. Thanks!
