I don't think you understand how his mind works: visually and mathematically.

that said measure the iris/spots/freckles/whatever the fuck else in the eyes and ignore all other data ...or heaven forbid, some holistic personality of ppl. what do they say. what do they do. what do they like. do they talk about relationships/one-on-one bs most of all or about the history of geology. what does their bio look like. it doesn't matter.

also he's coming from a very non-Sx vantage point ..he seems to completely disregard the energy ppl project and fixates only on that iris thing.
