You are making very big claims without adequate references. The study shows the effects of a one-off payment, to a highly selective group (note that I'm not implying their randomization was bad, but that both treatment and control groups were very special relative to the whole population), an a particular developing country.
You may personally believe that this is part of a general phenomenon that applies to highly developed countries, to all groups of people in that country, and in the long term not just the short term, but you have presented little evidence for the claims in your first paragraph (I read all the links).
You seem to view BIG as somehow unique, when in fact it is functionally equivalent to progressive taxation plus welfare, when welfare is only conditional on income. It is also hard to argue against because it treats redistribution, which is a sliding scale, as something absolute: it suggests an (imaginary) bar for "basic" income.
I personally believe systems where welfare is primarily conditional in income, but weakly conditional on searching for work or getting training (such as Australia's) are optimal for developed countries. The government can be far more generous when it adds some strings to welfare, than when it is simply giving out money. The only issue is whether countries with different governmental frameworks can copy Australia's model.
In short, you seem to be overlooking what I consider the real interest of this study, which is its specific relevance to developing nations.
>Please, anyone, show me some research that shows BIG doesn't work well. Cheers
That's a very asymmetric way to think about the evidence for and against a particular policy.
edit: The specific problem with your evidence, is that on a such a broad topic, I would expect to see an academic review of the literature. What you provided was [1] wikipedia, [2] an interesting example with no control, and [3] something that wasn't an actual academic study, but a description of a program and it's alleged benefits without any peer-reviewed study demonstrating these benefits.
