johnston: Most of your "arguments" are not even arguments.

Johnston wrote the above then went on to make the absurd claim below that 'conventional wisdom is almost always wrong, and, usually dead wrong', citing a link which does not bear that out; the link demonstrates that johnston describes himself when he writes 'most of your arguments are not even arguments'.

johnston, #75: Actually, conventional wisdom is usually dead wrong
Johnston: Also, conventional wisdom is almost always wrong.

Excerpts from johnston's link:

Title: Conventional wisdom often dead wrong

Duh, johnston, 'often' does not mean 'usually'; often is ambiguous & can range from most to some to relatively few. To equate often with usually is an error in reasoning, argumentum stupidium.

first usage in article of conventional wisdom: Stephen Dubner, .. whose work amply demonstrates his humor, willingness to challenge conventional wisdom, and passion for starting conversations.

Duh johnston, yeah it's OK to 'challenge conventional wisdom' which indeed sometimes does not have it completely right, but dubner is NOT claiming that conventional wisdom is usually wrong.

2nd usage of 'conv wisdom': And she (susan cain) chipped away at the conventional wisdom surrounding introverts, extroverts and success.

Right, but she's not saying that conventional wisdom is 'usually wrong', she's challenging it on a case basis.

3rd time: Sandel said the conventional wisdom that "markets are the primary instrument of achieving the public good" has been on the rise for three decades.. And America's unyielding faith in the power of markets - even in the wake of the financial crisis - is nothing less than a threat to our country's soul, he said

Sandel singles out market influence as being conventional wisdom, but is not claiming conv wisdom is 'usually wrong'.

HuffPo conclusion: All of these thinkers, in very different ways, reinforce an important lesson: that conventional wisdom, no matter how deeply held, is often dead wrong. When we assume that it is right, we limit not only the range of our debate, but our chances of arriving at the solutions we so desperately need.

Nowhere does the article claim conventional wisdom is usually wrong. It simply states that conventional wisdom needs be scrutinized to locate any potential flaws or inconsistenties or inapplicable applications.
Conventional wisdom says wash your hands after visiting the men's room. You wanna argue that johnston?
