"Gat [3] compared the run times, development times and memory usage of 16 programs written by 14 programmers in Lisp, C/C ++ and Java. Development times for the Lisp programs ranged from 2 to 8.5 h, compared with 2 to 25 h for C/C ++ and 4 to 63 h for Java (programmer experience alone does not account for the differences). The Lisp programs were also significantly shorter than the other programs."
Could selection bias be skewing these results?
Proficient Lisp programmers can certainly create shorter and faster programs with Lisp. Who would ever contest that? Average programmers, on the other hand, can probably develop in a similar amount of time and write faster programs with C++ (given the amount of libraries and information available - in comparison to Lisp - and the ubiquity of tooling).
