Question: Who develped the double-blind chart matching test?

Candidate passages:
Physicist Shawn Carlson put forward a double-blind chart matching test of natal astrology by using natal charts.
In the test, 28 astrologers, nominated by the National Council for Geocosmic Research, agreed to match over 100 natal charts to psychological profiles.
The experimental protocol used in Carlson's study was agreed to by a group of physicists and astrologers prior to the experiment.
The National Council for Geocosmic Research, acted as the astrological advisors, and helped to ensure, and agreed, that the test was fair.
They also chose 26 of the 28 astrologers for the tests, the other 2 being interested astrologers who volunteered afterwards.
The astrologers came from Europe and the United States., helped to draw up the central proposition to be tested.
Published in "Nature" in 1985, the study found that predictions based on natal astrology were no better than chance. 
Scientific Appraisal.
Carlson's experiment.
The Shawn Carlson's double-blind chart matching tests, in which 28 astrologers agreed to match over 100 natal charts to psychological profiles generated by the California Psychological Inventory (CPI) test, is one of the most renowned tests of astrology.

The Shawn Carlson's double-blind chart matching tests, in which 28 astrologers agreed to match over 100 natal charts to psychological profiles generated by the California Psychological Inventory (CPI) test, is one of the most renowned tests of astrology, and was published in a highly prestigious journal, Nature.
Double blinding helps to practically eliminate all bias from a study, including from participants as well as the person performing the study.

Sound quality.
Subjective evaluation.
Subjective evaluation attempts to measure how well an audio component performs according to the human ear.
The most common form of subjective test is a listening test, where the audio component is simply used in the context for which it was designed.
This test is popular with hi-fi reviewers, where the component is used for a length of time by the reviewer who then will describe the performance in subjective terms.
Common descriptions include whether the component has a 'bright' or 'dull' sound, or how well the component manages to present a 'spatial image'.
Another type of subjective test is done under more controlled conditions and attempts to remove possible bias from listening tests.
These sorts of tests are done with the component hidden from the listener, and are called blind tests.
To prevent possible bias from the person running the test, the blind test may be done so that this person is also unaware of the component under test.
This type of test is called a double-blind test.
This sort of test is often used to evaluate the performance of digital audio codecs.
There are critics of double-blind tests who see them as not allowing the listener to feel fully relaxed when evaluating the system component, and can therefore not judge differences between different components as well as in sighted (non-blind) tests.
Those who employ the double-blind testing method may try to reduce listener stress by allowing a certain amount of time for listener training (Borwick et al.
1994:481-488).
