Sorry, but no, not at all. I explicitly said "sometimes": "sometimes, low performance is low commitment or carelessness". My message since the beginning has been that, while not a great indicator, previous performance will at least have some correlation with future performance. Again, it's not great, but it's also not a random relationship.

I hope it goest without saying, you can and should try to have a deeper look at the context.
