Indeed, there are all types! There are certainly people who believe they can "beat" a computerized drawing, and hence want to keep them. It's a small percentage of people, but it does exist.
Personally, I think it has more to do with a lack of knowledge about computers than anything else. It is also an ignoring and/or disregard of the increased possibility of corruption and errors.
How many times in the past few of years have you heard of computerized drawings in which the drawings were flat-out corrupted? I have heard of several, and not just the Tennessee errors. Both California and Kansas come to mind. (News stories describing both of the major incidents are linked in my Favorites page, under Favorite Topics - second page of topics.) There is another story there about the Wisconsin Lottery drawing the exact same Lotto numbers twice within a 10-day span.
On the other hand, how many times in the past few years have we heard about ball drawings being flat-out corrupted? Anyone?
Sure, there are goofy errors, like if the balls slip out of the machine or something, but they stick 'em back in there and hold the drawing. And any operator of the drawing can clearly see that the error occurred -- with their own eyes. They don't need to hire an auditor over the period of several months and tens of thousands of dollars to report back that an error occurred.
By the way, how come the Tennessee Lottery -- Rebecca Hargrove, to put a finer point on it -- how come she is not mentioning that her computerized drawing systems has just taken away about $100,000 from education, and wasted it on an audit CAUSED by her mistake?
She always talks about scraping up every last dollar for precious education, but somehow blowing $100K doesn't get a mention from her? Does she REALLY care about education, or is it just the politically expedient thing to say?
If she cared about education wouldn't she make a deal to drop the computers and go back to balls, in exchange for getting rid of the audit?
