precise notion i come up with the number how liberal or conservative the media outlet is. is based on will called'' studdies. i call it the political quotient there are other measures but o is very conservative 100 is did the policy and 50 is my estimate of the average american voter with the blue dog democrat kind i'd like arlen specter. so i compare the media to speeches of the politicians. then i have the statistical method that gives the number to the content(ñ so what that

means is a "the new york times" will sound like good joe lieberman speech. although people call him the of moderate he is actually left of center he is midway between arlen specter and 90 pelosi. someone if it says "the new york times" would like the joe lieberman speech said he would have a 75 on the scale. >> host: give us one example how you got joe lieberman at 75 and then york times? >> okay. a recent example but the main way that i judge how

liberal or conservative his speech is or the media content is the think tank cetaceans. i have a list of 300 at think tanks from the heritage foundation, to the institute, those on the left. i tell the ratio with the "new york times." but but that sucks -- but that is from that that did it turns out joe lieberman would have the same ratio. in addis from more than the heritage foundation but that content sounds like the joe lieberman speech.

>> is content should be 50 from news sources? >> guest: i don't say that in the book. but my definition unbiased i'm the say something like c-span is 50 probably because a lot of your content is speeches from congress. it is very near 50. it is healthy to have it is healthy to have arranged! but it was close to 80 on

that scale. i am sure it would be even higher. >> host: what about fox news? >> really did one show. it was something like 39 it was definitely right-of-center. so that brett you show when not quite be left-of-center but not as wide as the average republican. some conservatives called them the right to leaning moderates. >> they call them the rino.

>> what about that methodology? >> it is involved and i pat myself on the back. is mathematical and computational sciences but that training alonesç would not have done them that did that i did their work forces attacking graduate school with a maximum likelihood of the technical term but is something you learn second and third year in the economics department, was proud to say i could use some of the things that i learned. >> host: is this written for a ph.d. is? >> guest: no. i have my mom in mind issue was the decorating mensch -- major so i was thinking of

her when i wrote it but it started with an academic article and that was fairly technical but i tried to say that one of my good friends is the author of economics. i of the first person to predict that but so i thought maybe i could do it. but you try to present it in the way people will understand my goal was to make it that way my wife says it is not but that was my goalms. >> host: is this the blast at the media? >> guest: someone. i tried to be objective the

be the epilogue guy did say one thing that was up last. the first few years of my career studying politicians i found a more steady politicians the more i respected them. studying journalist for the last eight or 10 years the last. how they could be more like politicians. or to be more transparent with their ideology. and with that average newsroom they interact very little. so politicians must@ interact

with conservative politicians because they stick together if they want to get anything done. >> with a couple of minor digs. >> host: what does the journalist personal bias affect his riding? >> guest: yes. the key thing with distortion method of bias. i don't think said journalist like to lessor told the un troops. but then the crimes of omission. it often happens. with the media research center said so that there

was the you to the video. but at the same time we have the clippers owner sterling both are equally persuasive but the white house is playing politics to make themselves look good for the election those are true but say it was much more important. but the sterling story is the one we should report more. and then select a different set.

and many "new york times" generaill list wy those facts. in the ideology in the and heart. >> host: professor tim groseclose offer of "left turn." are you a conservative personally? >> yes. by and in chapter five by discuss my views i think all journalist should do that i hope they do those standards >> host: is it a problem we have they know who they are getting. >> but the average journalist is 80 or 90 or 100 on my scale with the

applicableço quotient but they report on the slant quotient the mainstream media is 75 for 65 even though in their heart they would like to report into the '90s. so of they are moderating themselves but is there a problem with the bias? no. i think it is good to have a variety. it is overwhelmingly on the liberal side. especially with 50/50. >> with a conservative bin to a liberal newsroom?

>> i found this great story a reporter on minneapolis got a job and it turns out it came about as an experiment. about the conservative when the cell phone ringsz in to talk correlative before her. and to tell me about the story the cases of the sixth

he moms on the plane but and if her conservative values cause her to learn about that story? oh yes of course, you would not have done that extra legwork. bin to have those conservative views. >> host: you said those that support the democratic new money for president? >> people ask me that. but there is something in

the dna liberals. things like army officer of the liberals to not want to pursue that. but that small business that conservatives want to do but that very little structure so i don't think it is a conspiracy for some reason liberals want to go into journalism in conservatives don't. >> host: what do you teach here? >> political science tutti chief economic matt bids

from political science. but then i ask all my students to compute their score. looked at the 20 votes. bin at the end i say guess the professors score. most of them go with 100 beds with the average it was 60 they would guess i was the left-wing moderate average shooting for 50 but most professors lean to the left.

>> host: what about your students? >> it is ucla. i did some one of the poll but it was about 75 / 25 liberal. missiles during the bush kerry election. i think beverly hills is about the same. but just the reflection of the l.a. area. a little more than they would be when they're older. but the class that i teach

and the other thing we do these exercises of amok congress theqp son day pretend those democrats are a republican. as 40 percent republican inner 60% will live after the switch 45 / 55. >> host: by the time this interview airs you will be added different university. >> i will be up patriot at george mason.

>> host: on the fairfax virginia? >> i used to have the job fair 20 years ago. it is a little uncomfortable at times been one of the only conservatives on campus i had as suspicion one time when i was up for a raise but george mason in the economics department i think the rest of the school is pretty close to the university's but. >> host: working on another book? and then this is the expos

day i was on the faculty oversight committee. london insider report on the use of race. within that definitely help. >> "left turn" is the name of his book professor tim groseclose you are watching booktv on c-span2.

>> the name of the book is "the gamble" professor lynn vavreck when you hear the term game change in politics what does that mean to you? >> guest: that is the great question.ñ >> that fundamental shift and if you are behind the net looks like you will start losing. >> host: are there game changers in the elections? >> guest: there can be. recently? not so much but there could be one in the future.
