Definitions:

Natural Experiment

An observational study in which an event or a policy affects the variables of interest, allowing researchers to study outcomes without manipulating the study environment.

Lower Gas Prices

A decrease in the cost of gasoline, which can affect consumer spending, travel behavior, and the overall economy.

Lab Experiments

Controlled experiments carried out in a laboratory setting to investigate relationships between variables.

Scientist's Objectivity

The principle of conducting research and experimentation without bias, personal or otherwise, aiming for unprejudiced findings based solely on facts and evidence.
