Thanks so much for taking my test. If you appreciate the way I explore nuances and explain complex information, please consider checking out my other projects:
June 30, 2023 Update: On the final results page, I added some more information on how neurotype (i.e., autism) and culture can influence type. To read it, head to the results page, and hit the "+" box after "And here are some important things to keep in mind..."
June 21, 2023 Update: I finished the tailored results page for ENTJ's, including my two top tips for that type, which means all the 'N' types are now complete. I also went back and improved the pages for ENTP's, INTP's, INTJ's, and ENFP's to make them all consistent with strengths, challenges, and tips.
June 17, 2023 Update: I finished the tailored results page for INFP's, including my two top tips for that type.
June 14, 2023 Update: Minor usability updates to the homepage and elsewhere.
June 13, 2023 Update: I finished the tailored results page for ENFJ's, including my two top tips for that type.
March 12, 2023 Update: Biggest update in a while: I completely rewrote the strengths & weaknesses for every single type on the results page. Those hadn't changed substantially since I created this test many years ago, so these new descriptions better reflect the more mature, nuanced understanding of typology that I have today (though I'm still learning every day, so I'm always open to feedback: email@example.com).
November 21, 2022 Update: 1) I'm happy to report that my test has become increasingly popular all over the world, and I've had many offers to help me translate it into various languages. I appreciate the passion I've felt from everyone, but it's quite a large undertaking to translate a website like this. So, for now at least, I've added a link on the homepage to the Google Translate browser extension, which seems to do a pretty good job.
2) I adjusted some of the wording for the instructions on the results page. And, I reworded some of the Si function questions.
3) I've begun adding two of my top tips for each type. So far I've finished ENTP, INTP, and INTJ.
July 4, 2022 Update: In addition to a few small stylistic updates, I added a way to view your raw results after you finish the test. It'll tell you your exact numbers in each area. I know a lot of you like to share screenshots of your chart results on Reddit (and other personality typing communities), so I packed all the raw data into a small enough area that you should be able to easily screenshot this new section instead to share (since it's more precise than the charts). You can find it on the final results page at the bottom of the "Your Results: Cognitive Functions" section, just above the area where all the types are listed. Have fun! 🙂
January 2, 2022 Update: I updated the questions in the Se vs. Si portion of the test (as an ENTP with Si as my fourth function, I recognize that I sometimes have a blind spot around that function). Thanks to a visitor for inspiring this!
September 13, 2021 Update: Since I haven't heard about any more bugs, the main test is now what had been the beta described below. The old version of the test is still available here.
September 1, 2021 Update:
Please see my explanation of the beta below. Thanks for your feedback! I believe I've addressed the bug that many of you emailed me about where it would keep adding more points if you used the back button after completing one of the cognitive function sections.
This is the beta. Click here to return to the regular non-beta site.
August 15, 2021 Update:
Exciting news: I've implemented the two biggest requests I receive for this test.
1) I completely redesigned the interface on mobile for selecting between two choices. Instead of having to tap one of the five small dots to indicate "definitely A," "slightly B," etc., there are now larger buttons right under the choices A and B.
2) I added a "back" button so you can return to the previous question if you made a mistake or changed your mind. If you're on desktop, you can also use the left-arrow and right-arrow keys to navigate forward and backward (but please keep in mind that when you go back—whether with the button or the arrow key—you'll reset whatever you'd previously selected for that question).
These were some technically-complex changes, so I'll leave this as the "beta version" for a while in case you discover any issues. Please leave a comment here if anything looks off with the scoring, you notice any other problems, or you have any other feedback.
This is the beta. Click here to return to the regular non-beta site.
June 23, 2021 Update:
I revamped the detailed results page for ENFP's.
March 4, 2021 Update:
Three updates today:
First, on the final page of instructions in the intro, I wrote about some of the ways your type can be skewed by your life circumstances, and I made the suggestion to answer the questionnaire as your child or teenage self might have.
Second, I added a big new section to the top textbox on the results page (at the bottom of it). It has info about: using typology for good reasons rather than boxing people in, immature and mature versions of types, and whether or not your type can change over time.
Third, I completely revamped the detailed results page for INFJ's.
February 7, 2021 Update:
Exciting news: I added a brand new section to the test with four new questions (screens 29 and 30). Before this, the test only asked you questions comparing Te to Ti, Fe to Fi, Se to Si, and Ne to Ni. To be more thorough, the new page has a question each for comparing Te to Fe, Ti to Fi, Se to Ne, and Si to Ni. This should add even more precision to your results, and your old bookmarked results URL's should still work fine with the new version. If anything feels off with this new update, you can access the previous version here. Please email me at firstname.lastname@example.org if you have any feedback or notice any problems.
I also made a few small tweaks to hopefully decrease the page load time slightly. And, I added some links above to my other projects. Thanks again for visiting, and I hope you're doing ok with everything going on in the world!
October 1, 2020 Update:
I've updated the results algorithm for the first time in a few years. This is based on a combination of feedback from visitors (thank you!) and my own evolving opinions about the relative importance of each piece when calculating a person's most likely types.
The algorithm change isn't dramatic; but, among several changes, the most significant one is reducing the importance placed on the "type families" question toward the end (by the way, I also updated the descriptions of each of those families).
Any saved results URLs you have from the previous algorithm will automatically update to use the new one. And if you'd prefer to use the old version of the test, you can access it here.
P.S., Pro-tip for desktop users: you can use the right-arrow key on your keyboard to quickly advance through the instruction screens at the beginning of the test.
June 8, 2020 Update: Thanks for visiting. Do you have questions about race, racism, or the protests happening right now? If so, I'd like to humbly suggest another website I created that's dedicated to explaining race in America in an approachable, step-by-step way without judgment or politics. Thank you, and I hope you stay safe with everything going on.
April 26, 2020 Update: Redesigned the mobile version of this site. Thanks for sticking with it earlier when it wasn't as easy to use.
