If only that were true. For counter-examples, see Pokorny. It's been
suggested that all roots not attested in three branches should be
discarded as probably being wrong.

Similarly, with Nostratic reconstructions, even if the hypothesis is
correct, a great many proposed correspondences are wrong.
Unfortunately, I think in many cases we will not be able to tell which
ones are wrong. Some of us have to learn to work with noisy data.

You've dropped your detection threshold - you'll always have a lot of
false cognates. You'll have to cope with the fact* that, say, 80% of
your correspondences are wrong.

*The error rate will have to be an estimate rather than a fact - not
something that unduly bothers statisticians.

Patrick:

Essentially, I agree with everything you have written here, Richard.

But why as high as 80%?

That seems unduly pessimistic to me.
