The notion that one’s handwriting can evidence aspects of one’s character and predict likely behavior (“graphoanalysis”) is prevalent in some circles, including some Orthodox Jewish ones.
While I have no desire to interfere with the livelihoods of those who offers handwriting analysis services, I do feel a responsibility to offer accurate information to the public.
To that end, I feel it is worthwhile to share an article on the topic of “graphoanalysis” that I wrote for Ami Magazine back in 2011. You can read it here. Feel free to share the link with anyone you feel might find it thought-provoking.
