The fact that these people in said uniform assume that they have more Torah knowledge than a “pedestrian” out of uniform is, not only arrogant, but wrong.
Oh come on. The facts are true and based on very clear statistics.
There are more people learning for longer who dress like that. If we make the simple assumption that learning more is a good indicator of knowing more, we can easily say that a stranger has a better chance of being a talmid chochom if he is dressed like that.
That doesn’t mean it makes you a talmid chochom or is necessary to be one. It is just a siman.
Much like a fellow in a tweed jacket walking in Harvard Yard is more likely to be a professor than a guy in a suit in Manhattan. Wearing a tweed jacket doesn’t make you a professor, and wearing a suit doesn’t make you not one. It isn’t even a uniform. But if you’re looking for a professor, take my advice.
