Not all information is equally important though. Most people can't tell flac from a high quality lossy compression. If you cut off everything above 19khz and below 70hz you've lost information but not important information. The same analogy holds true about imagery. Which information is lost is important which is why I discuss clipping different levels and masking to make a stronger case. I'm just saying I don't think we can conclude an answer from this experiment, not that their claim is wrong. I want to be clear about that.
