The lessons I have learnt marketing an independent cohort-based online course.

Thread 👇 LESSON 1: START CLOSE TO HOME

Leverage your personal network to get the ball rolling. Then gradually move to your professional network.

Don't aim for the ideal target market if they aren't close by. Feedback and support in getting the course off the ground is key NB initially.

The lessons learnt building, marketing and running an independent cohort-based online course.

Thread 👇 Some context:

I began 2020 with the ambition to build a new kind of development programme.

THE PURPOSE OF THE PROGRAMME:

To provide people with a framework, toolkit and group platform for building behaviourally-informed systems to solve the recurring self-control challenges.

The lessons I have learnt building an independent cohort-based online course.

Thread 👇 LESSON 1: GET YOUR COURSE STACK RIGHT

There isn't a platform that meets all my needs as a cohort-based online course creator.

I've looked.. hard. Believe me.

So I use a combination of:

So happy @ShaneAParrish got @LFeldmanBarrett on his podcast. What a treat!

They explore Lisa’s incredible work on emotions, the predictive brain hypothesis, body budgeting, and the importance of focusing on our physical, mental and social health activities.

Big day for the field of Applied BeSci yesterday, with the launch of @gaabsorg 🚀

Curious what other researchers and practitioners think about it.

Some questions worth exploring 👇 What roles do you expect an Applied BeSci industry body to play? And roles should it not play?

Anyone know of any good resources (articles, papers, talks, etc) that get into the details of how to conduct a pre-mortem?

Thinking of writing something, but want to see what’s out there first. This is neat from @Atlassian

This is one of those papers I keep going back to.

(Especially when thinking about self-applied behavioural science)

'Beyond Willpower' by @angeladuckw , @katy_milkman and #DavidLaibson

Here are my favourite notes and quotes (Thread)👇 Timeless insight into why self-control is so tricky:

"Men are rather reasoning than reasonable animals for the most part governed by the impulse of passion." ~ Alexander Hamilton (1802)

Useful to remember that inquiry on the topic stretches back 1000's of years.

One of my favourite papers at the moment is @samulipo and #RalphHertwig's ~ Self-nudging and the citizen choice architect (2020).

Here are some of the ideas I found useful.

(Thread) 👇 How the authors define self-nudging:

"Self-nudging applies insights from behavioral science in a way that is practicable and cost-effective, but that sidesteps concerns about paternalism or manipulation."

Big thanks to @jasonacollins and @wrmailer for the invite to speak at the @SydneyBEnet meetup. Really enjoyed it, especially the questions at the end

You can download my slidedeck here: bit.ly/3bzxvC2

For ease, I've added the slides to this thread too.

Is applied behavioural science stuck at a local maximum?

My sense is that there is a set of technical and ethical limitations that are getting in the way of progress.

Here is how I'm currently thinking about these limits and ways to overcome them (when possible). Firstly, the Technical Limitations:

1) Replicability
2) Unknown Boundary Conditions
3) Complementary & Crowding-Out Effects
4) Cultural Variation
5) With-in and Between-subject Idiosyncrasies
6) Channel & Data Access
7) Implementation Issues
8) Unforeseeable Second-Order Effects

A thread on the emerging second order effects of #COVID19

I’ll add to the thread as new info surfaces. Feel free to add your thoughts and links too. Lockdown is leading to a rise in domestic and child abuse.

Curious about the effects of habit discontinuity.

Why did a 2 day disruption in London’s underground service permanently shift commuter habits,
Yet-
After 3 months of heavy restrictions/campaigns, Cape Town citizen’s water consumption habits returned to their pre-drought status? @ProfWendyWood @bjfogg @JamesClear @bermster @evelyngosnell @SamuelSalzer @BasVerplanken @katy_milkman @dilipsoman ++ it would be helpful to get your views on this.

A concerning observation made during the Cape Town water crisis: The negative second-order effects of shifting consumption habits.

E.g. Citizens were so focused on water, that plastic usage became an issue (myself included).

Thinking about #COVID19 through this lens
(Thread) Given the shift to physical-social distancing, less movement, remote work, and more time online (news, twitter etc), a set of unhealthy consumption habits could quickly emerge for many people.

#COVID19-induced myopia (attention tunnelling) means we ignore the habitual red flags.

Some of my favourite takeaways and quotes from
@owainservice and Rory Gallagher's book, Think Small.

The Surprisingly Simple Ways to Reach Big Goals.

(Thread ~ 1/n) 7 steps for long-term change based on evidence from the behavioural science literature:

1) Pursue a single goal (with clear targets + deadlines)
2) Set simple rules (bright lines - not drinking in the week)
3) Publicise your goal + appoint a commitment referee

Some of my favourite takeaways and quotes from
@bjfogg's book, Tiny Habits.

(Thread ~ 1/n) Positive change has less to with willpower and more to do with how we approach change.

Approach:
1) Stop blaming failure on a lack of willpower/self-control
2) Break aspirations down into bite-sized chunks

Long term change, requires a focus on tiny changes upfront.

Some of my favourite takeaways and quotes from
@ProfWendyWood's book, Good Habits, Bad Habits

(Thread ~ 1/n) What is a habit?
A mental shortcut to repeat what we did in the past that worked for us and got us some reward.

It turns out that people act out of habit a lot more than expected:

“Fully 43% of the time, our actions are habitual, performed without conscious thought."

(Thread ~ 1/n) Key idea: Small habits can have a considerable effect on your life, given enough time.
