Why Do People Persist in Believing Things That Just Aren't True

It’s the realization that persistently false beliefs stem from issues closely tied to our conception of self that prompted Nyhan and his colleagues to look at less traditional methods of rectifying misinformation. Rather than correcting or augmenting facts, they decided to target people’s beliefs about themselves.

Very interesting research here about why you're arguments and persuasive debates about a topic might be fruitless.

#psychology  
To change false beliefs, appealing to a person’s sense of self may be more important than the facts.

Our Nest thermostat has been working fine for the past year. Yesterday it disconnected from the WiFi and would not light up  when someone walked by. Low battery. I pulled it off the wall and stuck a USB charger on it. While I was waiting for that I did a few searches and read up on how it steals power when it can. It is a common problem for it to not keep up. The fix was to connect the 24VAC ground "C" wire. Apparently this ground helps it get charged much more reliably. Today the battery was fully charged.

I feel I need to get a nest CO2 alarm for upstairs, so the thermostat downstairs has a better idea of when the house is truly unoccupied. Unfortunately, my current CO2 (wired) alarm is downstairs, right next to the current thermostat location.

During dinner we heard water spraying outside. One of the galvanized fittings developed a hole right through the casting. This is a fitting I put on about 8 years ago. Makes we worry about the rest of the fittings and pipes. I assume it was due to the dissimilar metals causing corrosion.

The bronze faucet was above and based on the rust it looks like it was slowly leaking for a while before it let go.  I am thinking a combination of the water sitting for a long period of time, the galvanic effect, and possibly a cheap zinc coating on inside of the fitting. Definitely corroding from the inside out. I am unable to get the faucet off the fitting.

I pulled several shingles off the roof and sprayed where they were holed up. I verified three bodies. Several hours later I heard crunching from that same area under the eaves, I did not get all of them and will have to try again.

How one activity you do every day made the human brain possible:

It's surprising how much energy is consumed by our brains.  Now if only that consumption was proportional to the amount of thinking we do.  Then all of us computer scientists with desk jobs would be in amazing shape!

Okay, pretty much every one of these maps shows something interesting.

(When I was working for the World Health Organization's Global Programme on AIDS during college, I wrote mapping software to display various kinds of geographic data, so I've always liked maps that make some interesting data eminently clear).

8 day sailing trip to North Channel in Lake Huron. Very little wind, lots of mosquitos, granite sculptures left behind by glaciers, great dingy exploring, lots of wildlife, lock tour in Sault Ste Marie.

Yes, this is the area I sailed with my parents when I was a kid. It is different being there as an adult, so many rocks to avoid but GPS gives us the equivalent of local knowledge. The cold freshwater is great. We went early in the season so no one was around.

Most articles about gun violence that I've read recently seem to be based on emotions, not data. This one is different. I found it an interesting quick read.

That doesn't smell right.  Is the Daily Currant like the Onion?
