After reading this article, it validates what I've been saying.
You can have the right data, at the same time, you can have the wrong analysis.
Because people have inherent biases.
They may have personal business experience which can skew the results.
They may lack certain analysis skills which produce faulty results.
I say let the machine's analyse the data and produce the results.
Leaving the analysis up to error prone humans can be risky.
And so it goes!
