It's not really supposed to be pseudo-random.  It's supposed to show 
high correlation over short distances and near-zero correlation over 
longer distances.  To accomplish that, it uses a variant of Perlin noise.

If you want more randomness, consider playing with the lambda and omega
parameters to the turbulence.  See the documentation for more details.
