The points presented to you describe the differences between internal and external validity. In other words it is the extent to which the results of a study can be generalized to and across other situations people stimuli and times.
Internal validity we are making the experiment more and more artificial and thereby its generalizability external validity suffers.
Internal validity and external validity. External validity examines whether the study findings can be generalized to other contexts. External validity and internal validity often conflict Cozby 2014. Since internal validity is based on a cause and effect relationship between specified variables if that is what the researcher seeks to identify then there is a strong case for establishing internal validity Cozby 2014.
The concept of validity is also applied to research studies and their findings. For laboratory experiments with tightly controlled conditions it is usually easy to achieve high internal validity. When you claim high internal validity.
