New browser plugin stops people bamboozling you with numbers

Dictionary of Numbers provides that much needed context.

I've written before about how numbers without context are meaningless. Remember the claim that "every year in Spain alone… between 6 and 18 million birds and bats are killed by wind farms"? We're used to things that number in the millions being a lot, but without context, our intuitions can mislead us. So, for instance, if I claimed that "every year in Spain alone, between 6 and 18 million bytes of pornography are downloaded", your gut reaction might be that the Spanish are porn-hungry sex-fiends – until you realise that a moderately sized picture file is around one million bytes. That stat would in fact make Spain one of the most prudish countries in the world.

So, for the wind farm example, we found a few comparisons: in the US, power lines killed 130 million birds a year, while windows took between 100 million and almost a billion each year.

That's useful – and served to put some scaremongering at rest – but we can't all be looking up US Department of Agriculture papers when there's a potentially misleading statistic. So rejoice! For there is now a Chrome extension that can do the same thing automatically.

Dictionary of Numbers "searches through the page for numbers it can understand, and when it finds one, adds an inline explanation for that number in human terms". What that means is that a report of a forest fire destroying 297,845 acres of land is followed up by a little square bracket telling you "[≈ Hong Kong]"; something 100m high is [≈ height of the Statue of Liberty (foundation of pedestal to torch)].

As Glen Chiacchieri, the developer of the extension, writes:

One could write Dictionary of Numbers off as a tool for mathematically-inclined folk, but the fact is that understanding and reasoning about numbers is an essential part of modern society. After all, it's important to know just how much of the United States was on fire.

Sadly, the extension doesn't yet have any comparisons for the figure "8 million birds", so when it comes to dealing with the critiques of climate sceptics, we're still going to have to do it the old-fashioned way. And while it's handy for money in dollars, pound sterling leaves it upset and confused. But there's a third problem with the plugin, as well. As Randall Munroe reports:

It can also come across as unexpectedly judgmental. Glen told me about complaint he got from a user: “I installed your extension and then forgot about it … until I logged into my bank account. Apparently my total balance is equal to the cost of a low-end bicycle. Thanks.”

Donald Trump vs Barack Obama: How the inauguration speeches compared

We compared the two presidents on trade, foreign affairs and climate change – so you (really, really) don't have to.

After watching Donald Trump's inaugural address, what better way to get rid of the last few dregs of hope than by comparing what he said with Barack Obama's address from 2009? 

Both thanked the previous President, with Trump calling the Obamas "magnificent", and pledged to reform Washington, but the comparison ended there. 

Here is what each of them said: 

On American jobs

Obama:

The state of our economy calls for action, bold and swift.  And we will act, not only to create new jobs, but to lay a new foundation for growth.  We will build the roads and bridges, the electric grids and digital lines that feed our commerce and bind us together.  We'll restore science to its rightful place, and wield technology's wonders to raise health care's quality and lower its cost.  We will harness the sun and the winds and the soil to fuel our cars and run our factories.  And we will transform our schools and colleges and universities to meet the demands of a new age.

Trump:

For many decades we've enriched foreign industry at the expense of American industry, subsidized the armies of other countries while allowing for the very sad depletion of our military.

One by one, the factories shuttered and left our shores with not even a thought about the millions and millions of American workers that were left behind.

Obama had a plan for growth. Trump just blames the rest of the world...

On global warming

Obama:

With old friends and former foes, we'll work tirelessly to lessen the nuclear threat, and roll back the specter of a warming planet.

Trump:

On the Middle East:

Obama:

To the Muslim world, we seek a new way forward, based on mutual interest and mutual respect. To those leaders around the globe who seek to sow conflict, or blame their society's ills on the West, know that your people will judge you on what you can build, not what you destroy. 

Trump:

We will re-enforce old alliances and form new ones and unite the civilized world against radical Islamic terrorism, which we will eradicate completely from the face of the earth.

On “greatness”

Obama:

In reaffirming the greatness of our nation we understand that greatness is never a given. It must be earned.

Trump:

America will start winning again, winning like never before.

 

On trade

Obama:

This is the journey we continue today.  We remain the most prosperous, powerful nation on Earth.  Our workers are no less productive than when this crisis began.  Our minds are no less inventive, our goods and services no less needed than they were last week, or last month, or last year.  Our capacity remains undiminished.  

Trump:

We must protect our borders from the ravages of other countries making our product, stealing our companies and destroying our jobs.

Protection will lead to great prosperity and strength. I will fight for you with every breath in my body, and I will never ever let you down.
