Wow, this is like a case study on how not to present data. I'm sure this is an interesting dataset...but it's so confusing.
If you're going to have "ranked high" and "ranked low", make all the attributes positive.
I see in this thread that many people complain about it, so I've emailed author with the link to this thread and to Python's page and suggested renaming "Ranked high/low" to "Most people agree/disagree that..." or sth like this.
Otherwise, very nice idea.
