This is an interesting proposition. How do you test a "benign strain" of   
a virulent toxic meme? How do you contain it?
Imagine that a given meme-ecology, say the French body-politic (randomly   
chosen) needs innoculation against a virulent toxic-meme complex, say   
Nazism. How can you test a hopefully-benign strain of French National   
Socialism for efficacy? Do you later deliberately introduce virulent   
French National Socialism and observe for atrocities?
The penalties for failure are enormous.
Should we be trying to develop antibody memes for general application   
against widespread forms of antisocial behavior? What might such memes   
be, and what test protocol would demonstrate their efficacy? How do we   
locate a control group (uninfected) for comparison purposes?
I realize the above stretches the meme/virus analogy to difficult limits,   
and it may already break down in the above examples. If CofV is to create   
product memes that improve the global societies, however, I suspect that   
some type of resolution must be found for the questions/problems above.
What do you think, Tony?
Cheers!
