IAT Software · Designer and hosted administration

Design a seven-block IAT on Windows. Host it. Retrieve results only you can read.

This is software for Greenwald’s seven-block procedure. You build the test on the desktop — words or images, instruction screens, surveys before and after — and deploy it here. Participants take it in a browser. You get the file back. The people who run the server cannot read it.

I built the designer and the host so a lab does not have to write that stack. I will not contact you except about the address you verify, and only because authors can upload images.

Author on Windows. Deploy from the designer to iatsoftware.net. A product key and a verified email are required because tests can include images. The password that unlocks results is set at deploy and is not this email.

For researchers

Author the test in the designer. Deploy it to this host. Participants open a browser and take it. You retrieve an encrypted file with the password you set at deploy.

Someone with the database — including the person who runs this server — still cannot read that file. If that is the bar your review board cares about, read how the encryption works before you put identifiable answers in a survey.

How results stay private

For a class or a lab

Non-profit use is free and is not held to the one-test / 5,000 cap. That includes a course or a lab running under a school.

Email michael@iatsoftware.net and say you are running a class or a lab. There is no storefront and no invoice. I mark the account and you download the same designer.

For one test

You can run one test on this host at a time, up to 5,000 administrations, at no charge. You get trial latencies, survey answers, and a D-score in the Excel export.

That number is the standard scoring of this procedure. It is not a verdict about a person, and one administration is not a study. If you have not scored an IAT before, read the short explainer first.

What a D-score is

What it is

What it is not

It is not Project Implicit. It is not a library of ready-made social-attitude tests. It is not a web app you design inside the browser. It is not a platform for arbitrary reaction-time experiments outside the seven-block format. It is not anonymous-by-default — that depends on what the survey asks. It is not a test that uncovers hidden truths on first click.

Proof

Two screens from the designer. The rest of the tabs are on Docs and Samples.

Blocks tab in IAT Design, gender test after generate, with the stage preview visible
Blocks tab. Practice keys become combined keys on later blocks. Preview of the stage is on the right.
Deploy tab in IAT Design, signed in as Michael Janda, with retrieve, delete, and Excel export
Deploy tab. Upload, retrieve, delete, clear, and export. The password in the footer unlocks results.

How results stay private

Results are encrypted on the server so that someone with the database — including the administrator — still cannot read them. You choose a password when you deploy. That password is not stored on the host. If you lose it, the data is gone. That is the mechanism, not a support policy. Read how it works.
