A neuromarketing study takes three to eight weeks, and the brain scanning is rarely the bottleneck. Recruitment, scheduling, analysis, and reporting are where the calendar disappears, which matters because "how long" is really a question about whether you can afford to wait.

A typical study that involves brain scanning can take anywhere from 3 to 8 weeks, and sometimes longer. This timeline includes participant recruitment, study design, data collection, analysis, and reporting.

In contrast, AI-based prediction tools can generate results within minutes or hours after a video is uploaded. This speed difference makes AI tools more suitable for iterative creative work, where teams need faster feedback during the development process.

However, the faster turnaround of AI tools comes with a trade-off. They generally provide predictions rather than the deeper, participant-validated insights that traditional neuromarketing studies can offer. Teams often choose between speed and depth depending on their specific needs and budget.
