Is it true that conservatives are motivated by reason and liberals are motivated by emotion?

That is true. Conservative have a stronger foundation of fixed principles, liberals are transitory. If liberal thinking changes, it is changed by emotion. It is that emotional reasoning that allows for the famous democrat double standard, i.e. one set of rules for conservatives, a different and variable set for liberals. A recent classic is Joe Biden admitting to corruption on video and that is OK, by applying the emotional double standard, but to investigate Joe's corruption by republicans is corruption in itself. Even though the democrats have been investigating and trying to find corruption on the republicans for 3+ years. It requires a double standard.

No that is false. Trumpism is the politics of white grievance which is based on emotional appeals

Yes and you can see it happening in the current impeachment inquiry.

So far, Shifty Schiff has no hard facts against President Trump. The written evidence does not support his view and neither do the "witnesses". Not that many people being called as witnesses actually witnessed anything.

They just heard stuff from others and read the NYT and that includes the actual whistleblower.

Their evidence is full of how they felt. How something made them feel and what they thought. The libs are lapping it all up.

QED

No.  Most everyone is motivated by both in different ratios.

Case by case is the best way to determine an individuals motivation, imo.

No. That completely fails to explain why the vast majority of scientists are liberals.  For example, most of the national organizations of hard scientists fully support the fact that humans cause the recent uptick in global warming.  https://climate.nasa.gov/scientific-consensus/

Are you actually arguing that the American Physical Society & the American Chemical Society & the American Association for the Advancement of Science are all driven by emotion, not science, on the topic of global warming?

Nope, liberals are motivated by reason, which is why liberals back up their beliefs with science and logic

They're not liberals, they're leftists. 

But in answer to your question, no. The left is motivated by ignorance, inexperience and a failure to realize it. They're business 'experts' who have never run a business. Military 'experts' who have never served. Health care 'experts' who have no clue how health care is provided and paid for. 

Republicans don't suffer from such...and my concern is that ignorance seems to be a growing issue in the general population. 

LOL. Try saying something bad about guns, Trump or Yeshua Hamashiach right to their face. See how they'll react. They'll lose their shït, look at some of the threads I've been through in this very site.

They are pathetic because they can't accept that the world has moved on from a 19th century mentality.

The only thing I've seen motivate a liberal is free stuff.  

Both are influenced by reason and emotion also life experiences.  Both think they are correct.  I'm just being honest. 

Is it true that conservatives are motivated by reason and liberals are motivated by emotion?

No
