"decide to not go" and "try to not make mistakes"

[hirashin]

Dear native English speakers
My dictionaries say neither (a) nor (b) is correct. What do you think?
(a) I decided to not go.
(b) I try to not make mistakes.

Thanks in advance.

They don't look wrong to me. The only possible way I can imagine them being "incorrect" is based on the made-up "rule" against split infinitives.

you can flip "to not" to say "not to," and it would probably be considered... more correct... but most native speakers wouldn't bat an eye at this.

Thank you for the help, Nice gaijin-san.
To tell you the truth, the dictionary that says (b) is incorrect is Longman online dictionary. not | meaning of not in Longman Dictionary of Contemporary English | LDOCE

It says:
Not goes before ‘to’ in an infinitive verb.
You say: I try not to make mistakes.
✗Don’t say: I try to not make mistakes.

Maybe British people do not use this structure.

yeah, a grammarian would probably mark it as incorrect, and people who had it beaten into them as students might flinch, but no one would wonder what you meant. And you'll hear a lot of native speakers making this mistake.

It's like conbini keigo; at what point is it no longer considered "wrong?"

(a) I decided to not go.
(b) I try to not make mistakes.

I don't like (a) at all, while (b) seems marginally possible. Using "not to" in each case makes them perfectly acceptable.

I think both placements are correct. I don't see anything wrong with either usage.
