Intrasexual Competition Scale
Rivalry with your own sex is as old as courtship: sizing up who is more attractive, more successful, funnier, and minding when it isn't you. The Scale for Intrasexual Competition (Buunk & Fisher, 2009) measures that competitive streak in 12 statements. Read 'man/woman' as your own sex. Men and women score the same on average; compared with about 2,500 adults from eight studies.
Almost done!
Two optional questions, asked once: your age and sex let the results be broken down by who took the test.
Sex as at birth; gender as you identify. Languages you grew up speaking; several are fine, separated by commas. Leave blank anything you would rather not say.
