Idea Validation: Market demand, Willingness to pay
High Hurdle
Make the user experience more difficult to use to gauge keen interest

How: Make potential customers go extra lengths to get something done. The higher the hurdle, the more validity you can attribute to your results. Create a long survey, require an approval process, or create a similar hurdle that only users with a real interest will live through.
Why: Having users merely browse pages on a website does not validate actual interest in a product. Instead make users 'pay' by spending time and energy to go through a more cumbersome process to increase evidence strength and make the validation results more significant.
Make things hard to test gauge keen interest
Have the user go through a set of activities containing abnormal amounts of usability friction to gauge the customer’s desire for a particular solution. If they are willing to go through the extra high hurdle you put in front of them, chances are greater that they will also be willing to pay for it later.
If you are putting on an event, organize in a remote location with lots of travel time for attendees. Or gie them a lengthy online survey.
An added benefit of adding a lengthy survey to your sign up process, is that you can pre-qualify sign ups to ensure that users signing up are in fact exactly the right kind of customers for the product.
High Hurdle examples
Style profiles at Stitchfix
When users sign up for Stitchfix, a “clothing as a subscription”, they are asked to go through a lengthy sign up form that takes around 1 hour to fill out. Even though this seems as an uncomparable high hurdle to put in front of users, it serves another purpose: to reassure that the service provided is a serious one that needs elaborate data to work. This move plays on the Endowment Effect – the fact that we as humans have a tendency to place higher value on products we have invested- and feel ownership in. Ownership creates satisfaction.

Sign-up process
Design a sign-up process with multiple answers that are difficult to answer. This will increase friction to toward completing the sign up process and in turn constuct hurdle for customers to sign up that will ensure that only the most passionate customers are captured for your early testing. The purpose of this trick is alone to ensure higher evidence strength when conducting experiments. You will most likely not be interested in keeping the high hurdle in the product as you launch.
Financial Times
The FT conducted a high hurdle experiment by adding delays to their site for different user groups, to assess the impact on engagement. This approach helped gauge the true value users place on website speed, linking slower load times to decreased engagement and revenue.
