{Are justification and hyphenation good or bad for the reader?} {\regularorprogramstring{Leyla Akhmadeeva, Rinat Gizatullin, Boris~Veytsman} {Boris Veytsman}} {Since the early days of typography, text justification was considered a necessary feature of well-typeset copy. The type block should be rectangular and grey. Even the "New Typography" by Jan Tschichold, while rejecting many dogmas of classical typesetting, still retained text justification and, as a consequence, hyphenated text. In this work we study the impact of justification and hyphenation on the reading speed and comprehension. The participants in the experiment read justified and non-justified (and unhyphenated) texts and answered simple questions about them. We found the difference between the justified and unjustified texts very small. Still it is present: 1. Justified texts were read slightly faster. 2. Unjustified texts gave slightly better results in the recall tests. The probability of the correct answer for a multiple choice question increased from 0.89 to 0.93: this might mean four extra points on a 100-question test. }
