Fear of commitment of self-help, Harvard psychologist Deborah DePaulo has written books such as "Singleism" on the stigmatization of single people. The use of the term "fear" or "phobia" imparts an inherent linguistic bias. It recasts specific lifestyle decisions (such as bachelorhood vs. marriage, or a conscious decision to remain childfree by choice) implicitly as generalised, irrational phobias while failing to identify, describe or address an individual's specific motives. For instance, the men's rights movement, citing high divorce rates and expensive alimony and legal costs, would speak not in terms of "fear of commitment" but of "marriage strike" to reflect their position that
Irrational number A stronger result is the following: Every rational number in the interval formula_23 can be written either as "a" for some irrational number "a" or as "n" for some natural number "n". Similarly, every positive rational number can be written either as formula_24 for some irrational number "a" or as formula_25 for some natural number "n". It is not known if formula_26 (or formula_27) is irrational. In fact, there is no pair of non-zero integers formula_28 for which it is known whether formula_29 is irrational. Moreover, it is not known whether or not the set formula_30 is algebraically independent over
