Invalid Conclusion from Recent Sterilization Survey?

The Animal Welfare Institute said today in a news release that 77% of Americans oppose sterilization experiments on wild horses by the BLM.

However, the disclaimer at the end of the announcement said the poll was not based on a probability sample, taken to mean that the persons responding were not selected at random from the population to which the inference was drawn.

What the study did establish is that 77% of 2,027 U.S. adults who responded to the survey oppose the BLM’s sterilization research.
