Everything on this list, including this one, are just opinions. There aren't many "facts" when it comes to reptile care. Many different approaches have worked for people in the past. Keep an open mind and never be afraid to learn, and change your beleifs.
I see Jeff mentioned the Monitors. I had not realized it was "proven" either - but I won't get nit picky this time. Actually, I thought the whole lizard / uv thing was under a lot of debate, not just for nocturnal lizards.
