Common questions
How do examiners use slant drift as evidence?+
By charting the slant angle at intervals through a document, they can identify a trending reversion toward a hidden habitual slant, which points to a disguised writer rather than a genuinely different one.
Does slant drift ever occur in genuine, undisguised writing?+
Minor natural variation is normal, but a steady directional trend back toward one particular slant across a document is characteristic of a lapsing disguise rather than ordinary genuine variation.
