I won't invest in drug development companies where I think there may be a psychological effect on the patient getting "better".

vs.

I play Russian Roulette with oncology companies where, at the very least, I can see scans, follow patients, and look at pictures and see, what I feel, is working, or isn't working.

They're both forms of anecdotal evidence.

The "placebo effect" is broader and far more nuanced than just a patient's state of mind.

By definition, the placebo effect refers to any improvement that is not attributable to the investigational treatment. So it includes a variety of factors. My point is that even studies with more "objective" measurements are subject to the placebo effect.
