The world feels pretty divided.

Currently, 81 % of both liberals and conservatives have unfavorable views towards those on the other side.

But is there actually a fundamental biological difference between liberals and conservatives?

On the surface, we can see some funny differences like conservatives like meat and potatoes more,

while liberals tend to like trying food from other cultures more.

In general, conservatives prefer purebred dogs while liberals prefer mixed breeds, and liberals are okay with free verse poetry while conservatives prefer it to rhyme.

But as we study more, we realize that the differences are much deeper.

When put through MRI brain scans, it turns out that liberals are more likely to have a larger anterior cingulate cortex,

which is associated with understanding and monitoring conflict, while conservatives have a larger right amygdala, which helps process fear and anxiety.

And that makes sense, given the years of research

that have shown people tend to become more conservative when they feel threatened or afraid.

After 9 -11, for example, the US became politically more conservative, with studies showing increased support for issues like national security and military spending.

But studies have also found that conservatives and liberals employ different cognitive styles.

Conservatives excel when it comes to more structured and organized problems or questions, whereas liberals tend to be more flexible

and less likely to commit errors with questions involving conflicting information and requiring fast reaction times.

One study looking at dorm rooms even found that, on average, conservative students' rooms were less messy than liberals.

But they also experienced pain in different ways, so much so that one study was able to predict who was liberal

or conservative just by viewing brain scans of them looking at graphic photos containing mutilations.

In this instance, liberal brains were more active in the S2 or somatosensory 2 region, which is normally activated when you're in pain,

but also when you see someone else suffering.

It's essentially scientific evidence for the bleeding heart liberal stereotype, which doesn't mean conservatives are uncaring, but that their minds just respond to graphic images differently.

In America, this can explain how

Democrats and Republicans perceive the world in fundamentally different ways.

It's difficult to grasp how someone on the other side of politics thinks

because we tend to overestimate the extent to which our opinions, beliefs and values are normal.

Psychologists refer to this as false consensus bias.

For example, if you heard Yanny in the Yanny vs. Laurel debate,

it may have felt that you were the normal one and it was insane that anyone could be hearing Laurel.

Apply this logic to politics and you can see why people have such polarizing ideas on issues like immigration,

abortion, gun rights, etc. But where do these differences come from?

One study revealed that genetics can account for around 30 -40 % of a person's political leanings.

Which may seem like a lot,

but there are still many other important factors like your environment and personal experiences which play massive roles in your politics.

Political neuroscience is a relatively new field of study with fascinating results, and in a world that's being increasingly characterized by its divisions,

perhaps an important aspect of unity involves using neuroscience to better understand each other's differences.

On a lighter note, space is a place where liberals and conservatives and nations all over the world come together,

and we actually just made a video where we tried out the latest space food that astronauts are eating right now.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
