Concept

Fresh start effect

Dates that mark a beginning, such as a Monday, a new month or a new year, encourage us to start what we had been putting off.

In Spanish
Efecto nuevo comienzo
Origin
Dai, Milkman and Riis (2014)

What problem it addresses

It explains at what moments people are most likely to start a habit or a change.

An example

Gym visits by students at a university were analyzed over several months.

At the start of the weekAny other daybaselineWeek starts+33%Likelihood of going to the gym
The likelihood of going rises by 33%.
At the start of the semesterAny other daybaselineSemester starts+47%Likelihood of going to the gym
The likelihood of going rises by 47%.

It also rose at the start of the month and the year. Start dates work like a blank page.

Why it happens

  1. Start dates separate a before and an after.

  2. We feel our failures stayed in the previous period.

  3. And they make us look at our lives from a distance, so deciding on a change feels easier.

Applications in design

  • Use it like this

    Suggest starting at a natural beginning: Monday, the new month, a birthday or a new stage of life.

  • Avoid

    Using “new year” pressure to sell what won’t be used.

  • Don’t fall for it

    If you are going to wait until Monday to start, take the first step today.

+82%

What the research says

Rise in Google searches for “diet” at the start of the year. At the start of the month, they rose 3.7% (Dai, Milkman and Riis, 2014).

Solid evidence. These are data on real behavior, not from the lab.
