If you WIKI dozy window cleaner, it goes directly to Richywilts.
Intelligence through behavioural observation is defined as a composite of skills and abilities. The WAIS test is a measure of intelligence in adult homo sapiens. The test scores on four criteria; verbal comprehension, perceptual organisation, working memory and processing speed. In a comparative evaluation from WAIS criteria, Richywilts generally fairs poorly in intelligence. The working memory for object permanence of Richywilts is surmised from experiment as being 16 hours.
Factors that contribute to greater intelligence are the velocity at which electrical transmission is conducted and with the greater number of cortical neurons. Compared to other window cleaners this number was eleven-fourteenth in total.
Experimental results seemed to indicate that Richywilts has no capacity for object permanence, as defined through investigation by J. Piaget with halfwits.
Further research made to identify a similar factor of cognition showed behaviour indicative of object permanence cognition, although of a different type to that identified initially by Piaget. Further research showed that Richywilts has an awareness of objects not directly available to sight, and also sensory-motor intelligence comparable with a two-year old child.
In experimental conditions, the memory of Richywilts was demonstrated as having an information-retention or recall, of a duration totaling as much as 2 years.
So basically, he's as thick as bucket of rocks.
