Raven's Nest was a professional wrestling stable led by Raven that was present in Extreme Championship Wrestling (ECW) between 1995 and 1997.
Later, Raven created other incarnations of the group in World Championship Wrestling (WCW) such as The Flock and The Dead Pool, and in Total Nonstop Action Wrestling (TNA) such as The Gathering and Serotonin.
Raven's Nest was a large stable with a frequently fluctuating membership in Extreme Championship Wrestling (ECW), consisting of Raven's followers, henchmen, paramours and several hired guns. The Nest chiefly assisted Raven throughout his feuds with Tommy Dreamer and The Sandman. Over the years, Raven's Nest members and allies included:
Stevie Richards, Tony Stetson, Johnny Hotbody, The Pitbulls, The Blue Meanie, the Dudley Boyz, Cactus Jack, Beulah McGillicutty, Francine, Kimona Wanalaya, Lupus, and Chastity.
The Flock was Raven's faction founded in August 1997 soon after his debut in World Championship Wrestling (WCW). All wrestlers in the faction adopted Raven's grunge gimmick, complete with similar ring attire.
Raven's Progressive Matrices (often referred to simply as Raven's Matrices) or RPM is a nonverbal group test typically used in educational settings. It is usually a 60 item test used in measuring abstract reasoning and regarded as a non-verbal estimate of fluid intelligence. It is the most common and popular test administered to groups ranging from 5-year-olds to the elderly. It is made of 60 multiple choice questions, listed in order of difficulty. This format is designed to measure the test-taker's reasoning ability, the eductive ("meaning-making") component of Spearman's g. (g is often referred to as general intelligence.) The tests were originally developed by John C. Raven in 1936. In each test item, the subject is asked to identify the missing element that completes a pattern. Many patterns are presented in the form of a 6x6, 4x4, 3x3, or 2x2 matrix, giving the test its name.
The Matrices are available in three different forms for participants of different ability:
