gives me the idea, rank news items according to geographic distance, and "blast radius"

closer to you gives higher rank in the feed, tighter blast radius lower rank.

example, events in your present location rank higher, events 100miles away rank lower. police stopping someone for a seatbelt and issuing a ticket, likely ranks lower, vs evacuation order for city ranks higher.

a cheap way of assessing relevance score.

Neil Postman called this the “Peekaboo World”.

“What steps do you plan to take to reduce the conflict in the Middle East? Or the rates of inflation, crime and unemployment? What are your plans for preserving the environment or reducing the risk of nuclear war? What do you plan to do about NATO, OPEC, the CIA, affirmative action, and the monstrous treatment of the Baha’is in Iran? I shall take the liberty of answering for you: You plan to do nothing about them.”

Practically, focusing on the things you can change (mostly small scale evils in your community) will have the highest degree of positive effect, rather than focusing on stuff you are bombarded with online that is out of your control (mostly large scale evils).

However, don't think you get vindicated from duty just because the task is impossible. You are as just as much responsible for yourself, your family, your friends, your community, as you are responsible for the person living on the other side of the globe. Whatever you decide to do with that information is up to you, but you will suffer with any of those who suffer, whether that be in life or death. Only the delusional think they can escape righteous judgment.

stouset•1h ago
Righteous judgment according to which set of beliefs? Only the delusional are certain about anything that happens in the afterlife.
metabagel•1h ago
This is close to correct. We should be aware of current events but not become too emotionally involved with them. They are mostly outside of our control, and we need to reserve most of our focus and emotional energy on what is front of us and our loved ones. However, we should still act on behalf of greater causes with the means at our disposal. Some examples...

world in crisis - I donate to World Central Kitchen

the war in Ukraine - I donate to Come Back Alive

fascism in America - I vote for and donate to the campaigns of candidates opposed to fascism

appplication•45m ago
I was recently massively downvoted on Reddit because I mentioned I didn’t really care about candidates stances either way on Israel/Palestine as it regards to a city-level election. I certainly have opinions and understand why folks have principles either way, but we can’t make every issue the issue we spend our energy on, and this doesn’t meet the bar for me for a city official.

Sometimes online and election media discourse can feel like we’re supposed to be single issue voters on 1000 issues at once.

fn-mote•8m ago
In my ideal world, explaining this stance would be a part of democracy.

It’s an uphill battle vs a tribal mentality, though.

>We should be aware of current events

I have come to the conclusion that there is no way a layman understand the truth about current events. So it is best to not at all be aware of any current events as reported by the media or popular opinion.

For example you say "fascism in America", and I wonder is this guy for real? Fascism? If this was true how are all the people who insult Trump on social media still alive or not locked up?

So imagine if you were running a new outlet. All of your readers will unquestioningly accept your flawed narrative! And imagine there are multiple of such flawed/biased news outlets.

There is no way to know the truth. This is painfully clear when you read stuff in the news that you have first hand knowledge about...There is some name to the fallacy of why people still believe in news despite that...

applfanboysbgon•1h ago
This is a weird quote. It reeks of pretentious pseudo-intellectualism. People vote for a government that does something very tangible about all of those things. The media influenced how Americans voted in the US election, and they voted for a guy that predictably started a major new war in the Middle East. That is a real thing that happened and has impacted billions of people globally with second-order economic effects. Is anything short of each individual American taking up arms and marching to Iran "doing nothing"?
Paracompact•59m ago
My take on it is that he's not blaming people for the "doing nothing" part, but rather the fretting part. Of course most Americans can't reasonably do anything beyond vote or throw some dollars or social media sentiment at the thing. One should just take into mind that that is the limit of most people's ability to effect change.
threatofrain•21m ago
Which is enough to make the rest of the world hold their breath, waiting to see what the sum of little choices will be.
SpicyLemonZest•52m ago
People vote for such a government very rarely - in the US, about once every two years. I don't think anyone would object to you spending a week or even a month before the election learning a large amount about what's wrong in the world. But when you go into the voting booth on November 3 this year, do you expect your choices will be at all influenced by the details of the bad news you read on June 21?

I only read local news. It’s pretty nice I don’t feel stressed at all. Turns out random shit far away has no significant effect on my life. And even if it did it’s not like I can do anything about it
standeven•1h ago
The closing of Hormuz caused fuel prices to go up around the globe. Voting differently in the US could have prevented it.

So yeah, random shit far away can have significant effects, and sometimes you can do things about it.

That said, focusing on local news does sounds like a great approach, but international news still needs some attention.

pfannkuchen•1h ago
I agree with the sentiment generally, but there have been lots of times in history when recognizing that you should leave a place turned out to be life or death. The start of WW2 was random shit far away for a lot of people until it wasn’t.
eszed•11m ago
What's your last local news source? I'm jealous of you that you have one. The place where I live had their local newspaper bought out and (in effect) shut down by Alden Global Capital (google them) nearly a decade ago. There's nowhere to go to learn about what goes on in city council or school board meetings, short of attending or logging into their streams - which, at least it's good we have those, but is hardly practical for most residents.

I’ve been thinking about this a lot lately. Back in 2010 I gave a TEDx talk about how the internet can be an extension of your mind.

Nowadays I feel like it is contributing noise. The internet has become X, Reddit, AI, doomscrolling and group messaging.

Very little room for positive messaging. I don’t mean to harp about the theft of attention: the message itself is just not even contributing anything.

uberex•43m ago
Out of interest what is the path to talking at a TEDx?
isodude•29m ago
On reddit i have seen multiple threads that are positive through and through with topics like, "What are you up to today?", "I just finished school and starting to work", "I am lonely and feel dreadful". I read the comments and was met with level-headed and honest comments/interactions.

As in reality it's important to have walled gardens where people can utter opinions and voice their distress or just say that they are happy. Without getting lynched. These global silos of social media is nothing but deserts where the only way of getting through the noice with any means neccessary.

roenxi•1h ago
The other option is to be more realistic - people often have wildly unrealistic expectations of how the world should work and seem to get a bit stressed when they are confronted with reality.

The more pressing problem is the voters who accept policies being put in place based on something going wrong one time without accepting that things go wrong and we have to tolerate problems to some extent. If policies were made after a bit of experimentation, maybe trying a few things in parallel [0] and with prescribed objectives they were to be evaluated against the legislative process would get better results.

[0] The results of experiments like Shenzhen are significant. The US used to be a lot better at letting people act independently too.

One thing that really helped me was to start viewing my news media in black and white. Without the colored dressing, a lot of (especially partisan political) articles have much less emotional impact on me. Note: this worked particularly well for written media and less well for vocal media

SpicyLemonZest•30m ago
I think I like charts too much for text only, but this really does capture a common problem I have. A lot of articles seem to come with images that are almost designed to get the reader worked up. I think, at least in most cases, as a side effect, of selecting for reach and clickthrough rate? But that doesn't really help me and I'm not sure how to eliminate the "look how much of a jerk this guy is!" photos without also losing the charts.

"There are a lot more important problems than Sri Lanka to worry about. Well, we have to end apartheid, for one, slow down the nuclear arms race, stop terrorism and world hunger. We have to provide food and shelter for the homeless and oppose racial discrimination and promote civil rights, while also promoting equal rights for women. We have to encourage a return to traditional moral values. Most importantly, we have to promote general social concern and less materialism in young people."

TBH, we must concentrate on what matters to us. When people cross that boundary, they not only hurt themselves, but end up hurting someone close by for issues from far far away.

"We should be aware of current events" - should we? Why? There is an avalanche of current events, I've stopped paying attention and I still find out - its impossible to avoid, I see absolutely no value in paying attention to things that I'm just not interested in. War in Iran - yep, battle of the stupids - it just doesn't matter, there is nothing I can do about it, best to ignore it all. I have friends obsessed with the news, wake up in the morning and watch the news during breakfast - they discuss it endlessly, get a lot of angst from it, its all just noise to my mind.

Doing what you feel necessary or useful at a local scale is still empowering. Understanding that the effects will be mostly local as well is a good thing, but choosing your battles is perfectly healthy.

Thank you for your donations. World Central Kitchen is a really unique organization. In addition to feeding people in Ukraine, Gaza, and pretty much anywhere in the world where disaster strikes, they have a very unique model in which they employ locals and feed cash into in local businesses, generating economic impact to jumpstart the shattered economies in disaster zones. Your donations actually make a bigger difference than you might realize.
Candidates don't pop up out of nowhere on election day, and building support for either candidates or policies takes time, public debate, raising awareness. All of that is a reason for more political engagement, not less. Given how much power we actually wield to significantly influence how issues are approached in a democracy, we should strive to make more constructive use of the news. There are real, deep-seated problems with both the current media and how people consume it, but we have a civic responsibility to do better rather than disengage, because quite literally the fate of millions of people are influenced by the sum of our actions.
foxglacier•16m ago
You'd have trouble finding a candidate who wouldn't predictably start a major war in the middle East. Biden and Trump 1 were kind of exceptions. Kamala certainly seemed pro-war-in-the-middle-East with her support for Israel, so she's out. Who did you vote for instead?
