Objects to alien attitudes (7)

I believe the answer is:

mindset

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

'attitudes' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'objects to alien' is the wordplay.
'objects' becomes 'minds' (to mind something is to object to it happening).
'to alien' becomes 'et' (extra terrestrial).
'minds'+'et'='MINDSET'

Can you help me to learn more?

(Other definitions for mindset that I've seen before include "convictions" , "Characteristic mental attitude" , "thinking normally" , "fixed attitude" , "Outlook" .)

I've seen this clue in The Daily Express and The Times.
