But most of the empirical evidence thus far points to the contrary.

Of course, debate over empirical claims like these is normal and healthy.

This issue, I fully recognize, only concerns words, not the empirical world.

Again, however, more empirical data are needed to properly assess these relationships.

However, evidence to support these empirical distinctions has not been rigorously sought.

First, to test the validity of this argument we need empirical data.

This study reinforces a need for more empirical- and subgroup-specific research effort.

All previous work based on empirical criteria is, at least partially, incorrect.

The results justify the use of the scale in further empirical studies.

Further empirical research is recommended to explore the observations in this paper.

However, the empirical support for this claim has been weak or inconsistent.

The new scientific spirit was empirical, based solely on observation and experiment.

Results: There was a close match between empirical data and model output.

But this project wants to turn that empirical knowledge into a model.

The new spirit developed into the empirical and ideal systems of philosophy.

Recent empirical findings suggest a significant influence of emotion on memory processes.
