I believe the answer is:

trial and error

I'm a little stuck... Click here to teach me more about this clue!

'experimentation' is the definition.
(trial and error is a kind of experimentation)

'bring fear across rhode island american state' is the subsidiary indication.
I cannot quite see how this works, but
'bring' could be 'land' (landing is a kind of bringing) and 'land' is present in the answer.
'island' could be 'i' and 'i' is present in the answer.
'american' could be 'a' (common abbreviation - e.g. in organisation names) and 'a' is present in the answer.
'state' could be 'or' and 'or' is present in the answer.
This explanation may well be incorrect...

'may' is the link.
