Scenario: We are a supermarket that has a rewards card program and customers using this program exhibit positive behaviours (e.g. increased spending at our stores). It is assumed this is beacuse they are more engaged in the brand.
We want to increase spending for non-rewards customers (they generally spend less), therefore it has been suggested that we force everyone to get a rewards card in the hopes it will increase their spending too.
However these customers aren't as engaged in the brand, therefore their spending may not increase as expected.
To summarise, is there a word or phrase for the following sort of logic/process of thinking?
Trying to get people into a certain bucket/group because that bucket/group exhibits desired behaviours and expecting them to behave the same, even though they are different types of people.
This is of course doomed to fail as these are different types of customers and aren't going to suddenly change their behaviour.
A possible usage sentence may be (it's hard for me to guess since I don't know the word/phrase)
Although getting more people to use our rewards card to increase spending sounds like it would work, I think your idea falls victim to the following_____________.
