I was convinced this was already known and verified long ago. I've certainly told people this was True.

  You're thinking of the double slit experiment

    No, I'm definitely thinking of the fact that observation inhibits change in a quantum system. I'm fairly certain I was taught this was the case and was experimentally verified. 'Long ago' here means ~20 years ago.

      It says at the start of the article that it has already been experimentally confirmed for spin, this experiment confirms with respect to motion. I don't know when the spin one was done, maybe someone can provide more info. What I don't know is if the different quantum properties are independent of each other. If they are then presumably one would have to verify this Zeno effect on each property of a quantum particle. So maybe we can now say that the Zeno effect has been experimentally verified for two quantum properties now. Looked at this way you were both correct and incorrect. If spin and momentum are 'connected' in that if you experimentally verify some meta-property about one it verifies it for the other (such as, in this case, observing a property of a quantum particle freezes that particle) then this has been proved True and you were correct. Does this make sense? IANAQP.

        You can do this e.g. with photon polarization. Measuring here is very simple since it is achieved by sending your light through a linear polarizer. If you send light through a chiral medium, the orientation of the polarization would normally rotate. However if you measure the polarization often enough (by putting enough polar filters that are all oriented in the same direction in between), this rotation will not occur. This experiment is rather simple since you only need a standard optical bench and not any low temperature setup.
