Balloon Juice

Come for the politics, stay for the snark.

If you tweet it in all caps, that makes it true!

Republicans got rid of McCarthy. Democrats chose not to save him.

Republicans would impeach Biden if he bit into a whole Kit Kat rather than breaking the sections apart.

New McCarthy, same old McCarthyism.

If you are still in the gop, you are either an extremist yourself, or in bed with those who are.

“Look, it’s not against the rules anywhere, but a black woman with power was dating and there has to be something wrong with that.”

Speaking of republicans, is there a way for a political party to declare intellectual bankruptcy?

An unpunished coup is a training exercise.

“Everybody’s entitled to be an idiot.”

Incompetence, fear, or corruption? why not all three?

Republicans don’t trust women.

I’d hate to be the candidate who lost to this guy.

When your entire life is steeped in white supremacy, equality feels like discrimination.

Republicans don’t lie to be believed, they lie to be repeated.

Make the republican party small enough to drown in a bathtub.

This blog will pay for itself.

They traffic in fear. it is their only currency. if we are fearful, they are winning.

If you still can’t see these things even now, maybe politics isn’t your forte and you should stop writing about it.

Thanks to your bullshit, we are now under siege.

Chutkan laughs. Lauro sits back down.

I desperately hope that, yet again, I am wrong.

Dead end MAGA boomers crying about Talyor Swift being a Dem is my kind of music. Turn it up.

An almost top 10,000 blog!

It’s pointless to bring up problems that can only be solved with a time machine.

Cell Phones and Driving Again

Here is yet another cellphone study with some awfully surprising conclusions:

Using a cellphone — even with a hands-free device — may distract drivers because the brain cannot handle both tasks, U.S. researchers said on Tuesday.

Imaging tests show the brain directs its resources to either visual input or auditory input, but cannot fully activate both at the same time, the team at Johns Hopkins University in Baltimore found.

“Our research helps explain why talking on a cell phone can impair driving performance, even when the driver is using a hands-free device,” said Steven Yantis, a professor in the Department of Psychological and Brain Sciences who led the study.

“Directing attention to listening effectively ‘turns down the volume’ on input to the visual parts of the brain,” he added in a statement.

“When attention is deployed to one modality — say, in this case, talking on a cell phone — it necessarily extracts a cost on another modality — in this case, the visual task of driving.”

No kidding. While the innovative use of technology is cool, this is nothing more but what we have known for years.

    OK, If the distraction is a function of the auditory section of the brain, why hasn’t anyone tried to ban radios from cars.
    There has to be more to it than that.

    I’ve been pretty much saying the same thing you’ve said for a while now, and it’s not just that the conversation is a distraction, it’s that there are certain people who are gonna be distracted by SOMETHING, regardless of whether or not it’s a cell phone conversation and regardless of whether or not it’s in a car.

    My office is right in the city and most of the time i’ll just walk to client appointments, and i can’t tell you the number of times i’ve seen people yapping on their cell phones while they’re walking and end up almost getting smacked by a car because the person walking and talking doesn’t realize that the light is red and traffic is coming (apparently they’re so distracted they never noticed ten people all standing on the corner waiting to cross).

    If cell phones never would’ve been invented, these same nitwits would find other ways to be distracted while driving, whether it’s messing around with the radio, trying to light a cigarette, or whatever.

    …and why not ban talking to the passengers? For the children!

    It kind of reminds me of a study I read in college where, during orgasm, visual acuity goes down to like 30% and audiory acuity goes down to 50% (IIRC). So imagine how dangerous it is to be talking on the CELLPHONE while having an orgasm while driving. Go ahead. Imagine it. Pretty cool, eh?

    …and why not ban talking to the passengers?

    Personally, I find a cellphone conversation to be much more demanding of my concentration than a conversation with a passenger. My theory (which a proctologist with a flashlight will now show you the source of) is that talking on the phone requires the brain to visualize the interlocutor or otherwise create some sort of “virtual” representation which distracts it from attending to the actual sensory input.

    Driving can be divided into two phases: (a) turning, stopping, navigating, backing – operations requiring (or deserving) complete attention (turn off phones, tvs, radios, live talks in the car) and (b) the rest of the driving (waiting for traffic, long straight stretches on the freeway, etc.).

    Drinking pop, muching snacks, radio time, books on tape, talks with passengers, limited use of phones seem ok in (b) phases of driving, not in (a) phases.

    Safety talks need to make the distinction, no?
