Question 1

What is SciBLIND?

Accepted Answer

SciBLIND is a full-stack online experiment platform for behavioural and cognitive science researchers. It ships seven paradigms out of the box — Survey, Ranking, Discrimination, A/B Test, Reaction Time, Method of Adjustment, and Vignette — with publication-ready analytics, nine-locale participant UI, and deterministic replay via a per-session RNG seed.

Question 2

How much does SciBLIND cost?

Accepted Answer

SciBLIND has a free tier with 10 tokens per day for participants. Paid tiers start at 5 EUR. Researchers pay for the studies they publish; participants never pay. Tokens are shared across the ScAIentist® ecosystem (Cite, TechCheck, SciComic).

Question 3

Which paradigms does SciBLIND support?

Accepted Answer

Seven paradigms: Survey (Likert, multiple choice, open text), Ranking (ELO leaderboard from blind pairwise comparisons), Discrimination (categorical perception, accuracy + reaction time), A/B Test (between-subjects conversion), Reaction Time (Stroop, Simon, flanker, lexical decision, go/no-go, IAT), Method of Adjustment (Müller-Lyer, Ebbinghaus, Ponzo illusions), and Vignette (moral dilemmas, hiring scenarios, clinical cases).

Question 4

How does SciBLIND differ from Qualtrics, Prolific, or Gorilla?

Accepted Answer

Qualtrics is a survey tool; SciBLIND is an experiment engine with surveys as one of seven paradigms. Prolific is a participant panel; SciBLIND integrates with Prolific (plus MTurk and Bakker) for recruitment but is the experiment layer. Gorilla and Lab.js require building studies from scratch; SciBLIND ships seven paradigms with publication-ready analytics and a per-session RNG seed for deterministic replay.

Question 5

Can SciBLIND run experience-sampling (ESM/EMA) studies?

Accepted Answer

Yes. SciBLIND ships a full ESM/EMA scheduler with multi-channel prompt delivery (PWA push, Telegram, WhatsApp, email). Participants can snooze prompts from the notification itself. Schedules are configurable per study: fixed times, random windows, or signal-contingent.

Question 6

Does SciBLIND export to R, SPSS, or JASP?

Accepted Answer

Yes. Every study exports to CSV (long and wide formats) and JSON with methodology preamble and RT-quality flags. Exports round-trip into R, SPSS, JASP, and jamovi. A methodology-report PDF citing the platform version and RNG seed accompanies the data.

Question 7

Where is SciBLIND hosted?

Accepted Answer

On Hetzner in Germany, with nightly database backups and a public status page at scaientist.statuspage.io. Self-hosted PostgreSQL, no third-party database. Production URL: blind.scaientist.eu.
