This paper proposes a new analysis of indirect speech in the framework of game theory, social psychology, and evolutionary psychology. It builds on the theory of Grice, which tries to ground indirect speech in pure rationality (the demands of e‰cient communication between two cooperating agents) and on the Politeness Theory of Brown and Levinson, who proposed that people cooperate not just in exchanging data but in saving face (both the speaker’s and the hearer’s). I suggest that these theories need to be supple- mented because they assume that people in conversation always cooperate. A reflection on how a pair of talkers may have goals that conflict as well as coincide requires an examination of the game-theoretic logic of plausible denial, both in legal contexts, where people’s words may be held against them, and in everyday life, where the sanctions are social rather than judi- cial. This in turn requires a theory of the distinct kinds of relationships that make up human social life, a consideration of a new role for common knowledge in the use of indirect speech, and ultimately the paradox of ra- tional ignorance, where we choose not to know something relevant to our interests.

"A brilliant, witty, and altogether satisfying book."
—Michael Coe, New York Times Book Review

Everyone has questions about language. Some are from everyday experience: Why do immigrants struggle with a new language, only to have their fluent children ridicule their grammatical errors? Why can't computers converse with us? Why is the hockey team in Toronto called the Maple Leafs, not the Maple Leaves? Some are from popular science: Have scientists really reconstructed the first language spoken on earth? Are there genes for grammar? Can chimpanzees learn sign language? And some are from our deepest ponderings about the human condition: Does our language control our thoughts? How could language have evolved? Is language deteriorating?  Today laypeople can chitchat about black holes and dinosaur extinctions, but their curiosity about their own speech has been left unsatisfied—until now. In The Language Instinct, Steven Pinker, one of the world's leading scientists of language and the mind, lucidly explains everything you always wanted to know about language: how it works, how children learn it, how it changes, how the brain computes it, how it evolved.  But The Language Instinct is no encyclopedia. With wit, erudition, and deft use of everyday examples of humor and wordplay, Pinker weaves our vast knowledge of language into a compelling theory: that language is a human instinct, wired into our brains by evolution like web-spinning in spiders or sonar in bats.  The theory not only challenges convention wisdom about language itself (especially from the self-appointed "experts" who claim to be safeguarding the language but who understand it less well than a typical teenager). It is part of a whole new vision of the human mind: not a general-purpose computer, but a collection of instincts adapted to solving evolutionarily significant problems—the mind as a Swiss Army knife.  Entertaining, insightful, provocative, The Language Instinct will change the way you talk about talking and think about thinking.  New in 2007: The new “PS” edition contains an update on the science of language since the book was first published, an autobiography, an account of how the book was written, frequently asked questions, and suggestions for further reading.

English speakers disfavor compounds containing regular plurals compared to irregular ones. Haskell, MacDonald and Seidenberg (2003) attribute this phenomenon to the rarity of compounds containing words with the phonological properties of regular plurals. Five experiments test this proposal. Experiment 1 demonstrated that novel regular plurals (e.g., loonks-eater) are disliked in compounds compared to irregular plurals with illicit (hence less frequent) phonological patterns (e.g., leevk-eater, plural of loovk). Experiments 2–3 found that people show no dispreference for compounds containing nouns that merely sound like regular plurals (e.g., hose-installer vs. pipe-installer). Experiments 4–5 showed a robust effect of morphological regularity when phonological familiar- ity was controlled: Compounds containing regular plural nonwords (e.g., gleeks- hunter, plural of gleek) were disfavored relative to irregular, phonologically-iden- tical, plurals (e.g., breex-container, plural of broox). The dispreference for regular plurals inside compounds thus hinges on the morphological distinction between irregular and regular forms and it is irreducible to phonological familiarity.
