The IPIP is an example of a public domain scientific personality inventory that can be used for research.

  • Are there any good public domain scientific measures of intelligence?

Requirements

  • Do not link to the kinds of hits you get when you type "free online intelligence tests" into Google (i.e., tests where you can only do the questions and get summary normative feedback at the end)
  • Full text of instrument should be available, ideally with some form of test manual
  • Information about test has been published in a refereed journal
  • Test is freely available for use for scientific purposes, and ideally can be modified, adapted,

PEBL is a free open source programming language to help construct psychological experiments. A wiki and developer community provide some documentation and support.

PEBL has a Psychological Test Battery of many common or simple psychological tests so you may be able to use it out of the box without constructing your own test. PEBL includes free versions of many accredited and popular psychometric tests.

Many of them represent the only Free version of proprietory tests available anywhere. They include a free Iowa Gambling Task, a free version of the TOVA®, a free Wisconsin Card Sort Test®, a free version of Conners Continuous Performance task, and a number of other useful tasks, with more to come.

If one of the included tests does not suit your needs, you or a programmer can create your own tests with PEBL's programming language which is customized specifically to create psychometric tests.

I also think PEBL is great, but why is this the accepted answer? I only see some subtests that relate to IQ, but the PEBL tests don't meet your requirement #2, there are no norms. @Jeromy what did you end up using? –  Ruben Dec 5 '12 at 16:25
    
I just accepted the answer to show appreciation. I'm still open to further suggestions. For now, I'd still use proprietary measures for intelligence testing. –  Jeromy Anglim Dec 6 '12 at 0:30

PEBL has two main problems,

  1. It isn't normed, which means the external validity is going to be very weak.
  2. Standard computer hardware introduces random lag in timing measurements. Perceptual tests that measure raw neural speed and rely on millisecond measurements are meaningless.

That being said, I love the idea of PEBL and I have been thinking of some creative ways to norm the results on the cheap...
