It's not clear to me why the aim ought to be to sample randomly amongst all people - it seems like a different population could reasonably be chosen!

Sounds interesting. I had a go at the tool, but was a bit perplexed that the "lottery story" it showed me was for a Romanian earning $2,500/month, which doesn't seem like the kind of life that people's attention needs to be most drawn to or represents people that would be helped by effective development charities (it even says this person is at the 86th percentile of global income). And then below that it talked about ending hunger, eradicating disease etc., which didn't relate to the story. I'd focus it on stories about the kinds of people that effective charities would actually help. I tried to get it to generate another story to see what else comes up, but it wouldn't.

I guess it's hard to know without being in Mill's head. Though from what I've read it doesn't sound like he ever really wavered from favouring Britain having India as a colony.

I think this is an interesting analysis, but as others have indicated it could be better to frame this in terms of something like how these potential harms from saving human lives could be offset by donations to animal welfare charities, say.

Well, everyone will have their own emotional journey - not everyone with motivations to do good will have an experience like Mill's! But the point to not make improving social welfare the sole target and to have alternative sources of satisfaction seems to me quite common in discussions around EA and mental health, at least for those who do have difficulties.

I came across this extract from John Stuart Mill's autobiography on his experience of a period when he became depressed and lost motivation in his goal of improving society. It sounded similar to what I hear from time to time of EAs finding it difficult to maintain motivation and happiness alongside altruism, and thought some choice quotes would be interesting to share. Mill's solution was finding pleasure in other pursuits, particularly poetry.

Mill writes that his episode started in 1826, when he was 20 years old - but he had already been a keen utilitarian for 5 years and had been working for 3 years by this time, so was perhaps at a development point that not many would reach before they were into their early careers in the modern day.

From the winter of 1821, when I first read Bentham...I had what might truly be called an object in life; to be a reformer of the world. My conception of my own happiness was entirely identified with this object...This did very well for several years

But the time came when I awakened from this as from a dream. It was in the autumn of 1826. I was in a dull state of nerves...unsusceptible to enjoyment or pleasurable excitement...In this frame of mind it occurred to me to put the question directly to myself: "Suppose that all your objects in life were realized; that all the changes in institutions and opinions which you are looking forward to, could be completely effected at this very instant: would this be a great joy and happiness to you?" And an irrepressible self-consciousness distinctly answered, "No!" At this my heart sank within me: the whole foundation on which my life was constructed fell down...I seemed to have nothing left to live for.

For some months the cloud seemed to grow thicker and thicker...I became persuaded, that my love of mankind, and of excellence for its own sake, had worn itself out.

I frequently asked myself, if I could, or if I was bound to go on living, when life must be passed in this manner. I generally answered to myself that I did not think I could possibly bear it beyond a year. When, however, not more than half that duration of time had elapsed, a small ray of light broke in upon my gloom. I was reading, accidentally, Marmontel's Mémoires, and came to the passage which relates his father's death...A vivid conception of the scene and its feelings came over me, and I was moved to tears. From this moment my burden grew lighter.

I gradually found that the ordinary incidents of life could again give me some pleasure...and that there was, once more, excitement, though of a moderate, kind, in exerting myself for my opinions, and for the public good. Thus the cloud gradually drew off, and I again enjoyed life; and though I had several relapses, some of which lasted many months, I never again was as miserable as I had been.

The experiences of this period...led me to adopt a theory of life, very unlike that on which I had before I acted...Those only are happy (I thought) who have their minds fixed on some object other than their own happiness...followed not as a means, but as itself an ideal end.

This state of my thoughts and feelings made the fact of my reading Wordsworth for the first time (in the autumn of 1828), an important event of my life...[his poems] proved to be the precise thing for my mental wants at that particular juncture.

The result was that I gradually, but completely, emerged from my habitual depression, and was never again subject to it

Whilst I salute the effort and progress here, this post does seem rather full of spin, given that from what I can tell the court ruling was against the animal advocates. I'd rather see posts that present the facts more clearly.

They seem to say so in their intro video on this page: https://extinctionrebellion.uk/the-truth/the-emergency/. OK they say due to climate and ecological destruction, but it doesn't really matter for this. The point is just that disagreeing with experts doesn't generally seem to prevent an organisation from becoming "successful". (Plenty of examples outside climate too.)

It seems to be a big part in the UK cf Extinction Rebellion, Just Stop Oil.

One of the advantages of the climate protest movements is that they have a wealth of scientific work to point to for credibility.

Scientific work doesn't give particular support for the idea that climate change will create a substantial extinction risk though, and that doesn't stop the activists there. I'm not saying you're wrong or the OP's approach is justified, but public perceptions of activist groups' reasonableness seems only loosely linked to expert views (I've not seen much evidence of the "then they can go on to check what experts think" bit happening much).
