Techniques or Indicators scientists use to identify handwriting or forgeries

Scientists look for:

-Signs of Alteration, forgery, and (when sample documents are availible) handwriting or typing comparisons to determine or rule out authorship.

-Differences, not simularities.

-Style Characteristic vs individual characteristics.

*** Style characteristics are only useful for determining which copybook the writer learned from.

*** Individual characteristics are what matter most in determining authorship; they are unique to us and distinguish us from others.
