Take the tour ×  What is better to write?  that my results are
not reproducible that my results are unreproducible  How can it
be re-written as positive affirmation (preserving the same
meaning)?  Do not I remember correctly that it is better to
write negative sentence than positive but much more lengthy?
This question is about technical copywriting  Update: When I was
writing the question, I did not account for the fact that there
are 4 "synonyms":    • non-reproducible,   • unreproducible,   •
irreproducible,   • not reproducible  the post with this phrase
that provoked this question  share|improve this question "It

mean by positive affirmation? (Somehow, I'm reminded of Dave
Barry: 'WRITING TIP FOR PROFESSIONALS: To make your writing more
appealing to the reader, avoid “writing negatively.” Use
positive expressions instead. WRONG: “Do not use this appliance
in the bathtub.” RIGHT: “Go ahead and use this appliance in the
bathtub.”') –  Shreevat
