Winer (1999 [this issue]) proposes that external validity concerns require more attention in theoretical research. The author argues that one cannot “enhance” external validity by choosing one method over another. External validity can only be “assessed” by better understanding how the focal variables in one’s theory interact with moderator variables that are seen as irrelevant early in a research stream. Findings from single real-world settings and specific sets of “real” people are no more… Expand
Theory-Testing, Generalization, and the Problem of External Validity*
External validity refers to the generalization of research findings, either from a sample to a larger population or to settings and populations other than those studied. While definitions vary,Expand

It is often argued that experiments are strong on causal identification (internal validity) but weak on generalizability (external validity). One widely accepted way to limit threats to externalExpand

Context may be King, but generalizability is the Emperor!
TLDR
This commentary generally agrees with the notion that context should matter more in IS research; yet, the importance of generalizability in research should not be downplayed and should be given higher position in the scientific process and be the ultimate goal for researchers. Expand
Threats to the External Validity of Brand Extension Research
The findings of prior research suggest that a brand's extendibility is constrained by the degree of perceived fit between the brand and extension product categories. However, there are many examplesExpand

TLDR
I think that the generalization is actually particularized in an individual patient, and therefore I agree with Altman and colleagues' conclusions, and hope that they will state whether the target of validity is the individual patient or the population. Expand

TLDR
A framework based on widely accepted standards for evaluating participant choice is presented and provided, providing rationale that the choice is appropriate and how to improve the treatment of participant choice when evaluating the validity of study inferences is recommended. Expand

The Role of External Validity in Theoretical Research
Calder, Phillips, and Tybout (1982) have criticized my analysis of the role of external validity in theoretical consumer research (Lynch 1982). In particular, they disputed my argument thatExpand

TLDR
The author argues that external validity concerns should be given more attention in TA research and consumer behavior articles should be required to have a section indicating how increased levels of external validity can be obtained with other studies. Expand
