Chemistry / Re: Should you rinse detergent off dishes after washing them?

Aside from the chance of gaining a stomach ache and/or diarrhea, the basic mechanism of how soap works would be enough to get me to rinse off the dirty dishwater.
Soap removes grease and dirt(salty, sugary) things from your dishes. Each lauryl (soap) molecule has a non-polar end for greases and oils, and a polar end for salts and sugars. These soap molecules surround the oils and dirts by which ever end of the molecule is needed.
So when the dishes are not rinsed, those greases and dirts are being left on your dishes, with the 'bonus' of the soap as well. Hope this helps your proposal.
