But it kind of does in a statistical measure.

If you think in the systems of how criminals work, they tend to spend more time stealing things they think will pay off. Taking something that will cost them time and not gain them money will over time bias thieves to not taking iphones.

For example it may prevent this

a) iphone is left on a table in the open.

but would not prevent

b) iphone is in a bag, bag gets stolen.
