May I remind people that the intelligence of the LSE is entirely unrelated to said type. Stupidity or dimwittedness is not a necessary criterion for an LSE. It is simply a stereotype of a practical-minded, non-academic simple liver. Not all LSEs are like this. Many are intelligent. At the same time, there will be many unintelligent LSEs. There can be unintelligent ILEs as well as intelligent ones. The same applies to SLIs, IEIs, LIEs, ESIs - whoever.
