The "Doctors have messy handwriting" trope derives from the fact that prescriptions often contain a large fraction of Latin terms, chemical names, abbreviations and acronyms that don't parse (and thus seem sloppy/illegible) if you are trying to "decipher" them as English. Doctors don't have significantly messier handwriting compared to similar populations (esp. now that drafting isn't as emphasized in architecture, engineering, and similar programs)
>>>Doctors don't have significantly messier handwriting compared to similar populations
I'm skeptical of this claim. My family doctor had bad handwriting, and one time the hospital worker had to call him to ask if he ordered a x-ray or Ct scan.
Please. I still have my medical charts from my childhood, back before the computers. I can barely read the handwriting there, and it's not because of medical terms.
Apparently, it became slightly better recently, now that doctors spend less time scribbling things and mostly type them instead.
