Effects of Documentation Errors On User Perception of Interactive Programs: Background For a Study  

Typographical errors and grammatical blunders affect the aesthetic appeal of documentation, and common belief is that they affect usability too. Many readers, however, seem not to notice such errors unless they are very frequent or flagrant. We thought it would be interesting, and perhaps useful, to test experimentally the effect of such errors on users’ perception of the information and on their performance with the product that the information supports the product.
