The premodifiers 'ethics' and 'ethical' seem to be used interchangeably in the context of
- 'ethics review' / 'ethical review'
- 'ethics committee' / 'ethical committee'
- 'ethics approval' / 'ethical approval' ....
The same seems true for stacked premodifiers:
- 'ethics review committee' / 'ethical review committee'.
I can't decide which one to use, because I think the first covers the load best whereas the second is used most.
To me, the variant 'ethical committee' means that the committee is ethical in their behaviors and procedures and such, whereas the variant 'ethics committee' would mean a committee that concerns itself with ethics. Which is what the term should indicate.
Likewise, 'ethics review' seems to me to mean the review of something vis-à-vis a certain code of ethical conduct, whereas 'ethical review' seems to mean a review that is in itself ethical. Given that all of these terms are used to mean a committee/review/approval that is concerned with ethics rather than are ethical in and of themselves, I would think that the correct term to choose is 'ethics'. However, the term 'ethical' seems to be used the most.
I would greatly appreciate your help in figuring out what the correct premodifier to use in this context is.
