Examine reported taste experiences of synesthetes when exposed to various non-gustatory stimuli, like colored lights or sounds.

Compare reaction times between synesthetic individuals and those without the condition under similar conditions without connection to flavors or perceptions thereof.

Track eye movements of people with synesthesia while they watch moving objects with no link established to taste sensations.

Conduct memory recall tests under varying noise levels for normal individuals and synesthetes alike without focusing on tastes.

Garcia's theories accurately explain all aspects of humans' aversions or preferences for certain tastes.

They neglect to consider social and cultural influences on eating habits.

They wrongly suggest that animals have more sophisticated taste receptors than humans do.

These theories overestimate the role of classical conditioning in shaping our dietary choices.

Studies showing variability intensity reported sensations associated known tastants disparate regions suggest environmental factors play integral role alongside genetics determining degree supertaster phenomenon manifests person

Asserting that because animals use chemical senses, so must humans without substantial supporting data

Stating that pleasant smells are universally preferred, without cross-cultural studies.

Citing olfactory mechanisms shared across species as proof of evolutionary continuity

Claiming all creatures dislike foul smells because it indicates danger or decay

Double-blind taste tests with diverse samples.

Self-reported questionnaires about favorite dishes per culture group.

Open-label surveys on preferred spices by culture.

Observational analysis in public dining areas by culture.

Employ a double-blind procedure administering varying concentrations of bitter compounds, then measure detection thresholds and self-reported ratings from both groups.

Conduct genetic screening on a diverse population sample to identify PROP taster status correlations with reported dietary preferences for bitter foods.

Distribute online questionnaires asking participants about their general preferences regarding bitter tastes without specific compound testing or controls for taster status.

Use MRI scans comparing brain activity between supertasters and non-tasters when consuming commonly bitter foods like coffee or dark chocolate.

Observe and record behaviors of animals in natural habitats to infer human responses to repeated scent exposures.

Conduct a longitudinal study where participants are repeatedly exposed to similar scents at regular intervals, assessing changes in scent discrimination.

Analyze historical data on perfume sales to determine trends related to olfactory fatigue.

Survey a large sample of individuals on their experiences with olfactory fatigue without experimental exposure to scents.
