Those groups also have another characteristic that changes: the amount of the cow covered in paint.
How do you determine if its that vs the stripes or colors?

SmoothLiquidation@lemmy.world 5 weeks agoI haven’t read the study, but most of these would need a placebo group, so divide the herd into thirds, one with no paint, one with stripes, and one fully painted white to get a baseline for each group. Also would be good to randomize which group each cow goes in each day so to rule out one cow who is especially tasty to flies.

You paint a second control group the colors and patterns they already are

Did this study do that? The abstract didnt mention it.

Probably not. I was just answering your question - that’s how you’d eliminate that variable from the experiment

Also blindfold the scientists and the cows so it’s double blind. We don’t want the cows acting in a fly-attracting way because of placebo.
