Confirmation Bias
Confirmation bias is the tendency to search for, interpret, favor, and recall information in a way that affirms one's prior beliefs or hypotheses. It is a type of cognitive bias and a systematic error of inductive reasoning.
Sampling Bias
In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower sampling probability than others.
Recall Bias
In epidemiological research, recall bias is a systematic error caused by differences in the accuracy or completeness of the recollections retrieved by study participants regarding events or experiences from the past.
Publication Bias
Publication bias is a type of bias that occurs in published academic research. It occurs when the outcome of an experiment or research study influences the decision whether to publish or otherwise distribute it.
These are just as few Bias's. Bias is human error. Now add to that variables. There are many variables when studying wolves. Weather patterns change year to year, disease's come and go year to year. Landscape change, and a list of others that all need to be taken into account.
However it is undeniable that Wolves have had a major impact on ungulates. A 100+ pound animal needs to eat. Wolves are Carnivore's so that means hunting and scavenging. Both of which require a large amount of ground to be covered. Which requires energy, energy = food = animals!
Wolves are not the only Problem, but they are a Problem. They need to be managed and managing wolves is no easy task. Or should I say cheap task either, collaring and shooting requires helicopter time. That is not cheap!
