Text reads: About synthetic panels
Recruiting the right participants for a study can be difficult. You may not get the exact demographics you need, and the shorter the deadline, the less sure you can be that everyone will answer on time. One possible solution can be to use synthetic panels.

Synthetic panels are powered by a first party proprietary AI model developed here at Qualtrics. Our synthetic panel is trained on thousands of responses from a variety of demographic backgrounds in order to more accurately predict how certain populations would respond to a survey.

Our synthetic panel is based on the United States General Population, and is only available in English. This panel comes with ready-made quotas and target breakouts in order to represent your chosen population and make it easy to launch your survey right away.

Question-writing best practices
To get the most reliable and actionable results from synthetic audiences, consider these question-writing best practices:

Ask forward-looking and attitudinal questions.
Synthetic panels perform best with perceptions, preferences, and intent-based questions. For example, “How likely are you to try…?”
Synthetic panels are less applicable for studies on past behaviors, detailed recall, brand recall, or awareness questions. For example, “When did you last visit…?”

Discussion
The current study aimed to conduct a meta-analysis of the TPB when applied to health behaviours which addressed the limitations of previous reviews by including only prospective tests of behaviour, applying RE meta-analytic procedures, correcting correlations for sampling and measurement error, and hierarchically analysing the effect of behaviour type and sample and methodological moderators. Some 237 tests were identified which examined relations amongst model components. Overall the analysis indicated that the TPB could explain 19.3% of the variance in behaviour and 44.3% of the variance in intention across studies. This level of prediction of behaviour is slightly lower than that of previous meta-analytic reviews which have found between 27% (Armitage & Conner, 2001; Hagger et al., 2002) and 36% (Trafimow et al., 2002)
of the variance in behaviour to be explained by intention and PBC.

Did you know that from tomorrow, Qualtrics is offering synthetic panels (AI-generated participants)?

Follow me down a rabbit hole I'm calling "doing science is tough and I'm so busy, can't we just make up participants?"

A three by four grid of example stimuli found in the experimental buffet. The first column shows edible insects: meal worms, crickets, and buffalo worms. The second column shows novel savoury snacks for participants in the UK and Austria: Haldiram's Mullu Murukku, roasted broad beans, and Wah-Yuen fried dough. The third column shows common savoury snacks for the same participants: tortilla chips, crisps, and peanuts. The last column shows visually matched non-foods: Lego, wooden buttons, and wooden clothes pegs.

Figure with four panels. In each panel, the x-axis depicts the four types of stimuli: insect snacks, novel snacks, familiar snacks, and non-food. The top two panels show total dwell time across the experiment and average fixation duration. Overall, participants looked at the insects and novel snacks more than at the familiar snacks and non-food. The bottom panels show disgust and desire-to-eat ratings. Insects are scored as much higher on disgust and much lower on desire to eat compared to novel and familiar foods (both of which are rated low on disgust and relatively high on desire to eat).

Quick post on @jonaspotthoff.bsky.social new paper! We found people looked more at novel foods at an experimental buffet, including insects that they find gross! People suppress disgust avoidance when making foraging decisions.
