The same could be said about homeopathy, but homeopathy is a scam.

The problem is, how do you define "if there's an effect"? A placebo can not have an effect, yet, it has.

The whole point of placebo is that it has an effect though, just not one based on a real change.

That won't work for immediate relief; placebo is studied statistically as a cumulative change over a period of time. Not when I put Gunnars over my sore eyes from computing too much and get immediate relief. Frankly, I find this discussion a bit insane, a bunch of people trying to persuade me "it's all in my head" because they align with the opposite opinion, not with reality.
